Pepsi cola p e p s I that's your smartest colabi. Pensacola presents Counter Spy. Washington calling David Harding Counterspy Washington calling David Harding. Counterspy Harding Counterspy Calling Washington. United States Counter spy especially appointed to investigate and combat the enemies of our country both at home and abroad. Tonight, the case of the Cold Blooded Professor. Another Counterspy report to the American people, brought to you each Tuesday and Thursday by Pepsi Cola. Pepsi Cola. It's a spot. Two full glasses.
B
That's a lot.
D
That's right, you heard what they said. Two full glasses of sparkling Pepsi from one big 12 ounce bottle. You're getting an extra glass full. And what a delicious glass full. The most refreshing, delightful cola that ever tickled your taste. You can't top Pepsi's tangy flavor. And that big big bottle saves you money, goes twice as far. Pepsi is America's big big favorite and America's biggest cola value. So why take less when Pepsi is best? Whenever you reach for refreshments, remember why take less when Pepsi's best? And now to counterspy. The sun was just fading and the shadows were disappearing along a country road about a hundred miles west of Chicago, on the outskirts of a certain college town, Lipton, Illinois. A large black sedan moving slowly came to a full stop and the driver spoke To a farmer beside the road. Say, I wonder if you can tell me. That house up on the hill there for rent? Oh, no, that's the professor. Oh, professor who?
B
Horn.
D
Professor Horn. He teach at the college here? No. Everybody says he's a genius. Writes big articles for scientific papers. Inventor, too. How long does he live there? Oh, about five years. Nice fellow when he comes to town. Nice smile. Folks like him. He have many visitors? Don't seem to like visitors, mister. Got a lady housekeeper, though. She a nice person? Oh, you can take her. Leave her about 50. Homeless? Good, I guess. But homely. Old is professor horn? Oh, pressing 57 hard, maybe. Say, you want to know an awful lot, mister. Going up there? I might. Thanks for the information. Goodbye.
B
Professor Horn, where do you want these books to go?
D
The left hand shelf, Anna, next to the books on nuclear fission.
B
Must say, I'd be glad to see a plain, ordinary novel in this library.
D
For once, my dear, the only books worth reading are scientific, factual work.
B
Look at these. The Anatomy of Toxicology. Treatise on Molecular Growth and Decay. What's this one?
D
My scientific diary. I'll put that one away in that
B
closet you never wanted me to look in. Or you should let me do that. Your lame leg gets tired so easy.
D
You know I never want my leg mentioned, Anna.
B
And I never could understand why you won't let me go down cellar and see some of your inventions.
D
I have a lifelong principle, Anna. Better to anticipate than to regret. Meanwhile, please bear in mind that I pay you well and this does not include your asking questions.
B
Somebody's at the door. There's a black sedan in the driveway.
D
Go see who it is. But don't bring anyone in unless absolutely necessary.
B
I won't, Professor.
D
Close that door, Anna.
B
Of course.
D
Yes, I'd like to see professor horn, please.
B
He's busy.
D
My credentials.
B
Ld cameron, united states counter spies. This way, Mr. Cameron.
D
Thank you.
B
Professor Horn, Mr. Cameron of the Counter Spies.
D
Thank you, Anna. That will be all. Mr. Cameron. I live on an ironclad schedule. I should now be in my laboratory downstairs, hard at work. I trust you can debrief. Two nights ago, at 11:07pm in Amberville, 42 miles south of here, the Farmers Exchange bank was robbed of $121,000 in cash. The robber used a very ingenious electronic method of silencing the vault alarm system. However, the car used by the robber went through a puddle of oil and left certain tire tracks. Am I being brief enough? No, but continue. Every garage within 50 miles of Amberville has been Checked for a car with those treads. The car in your garage has those tire treads. That's a coincidence, Mr. Cameron. That's no coincidence. Professor Horn, I'm placing you under arrest on suspicion of robbing the Amberville Bank. Now this is upsetting. Mr. Cameron. Leave that drawer alone. Put your hands in the air. I said put your hands in the air. As you say.
B
I heard a shot. What happened? Oh, I see. How do you shoot him? There's no gun in your hand, Professor.
D
See under my coat, Anna. My invention. Small, flat, handled gun strapped alongside my chest.
B
And a wire up through your sleeve.
D
When I raised my hand, fired the gun. Now, no more questions. We're leaving. Anna, help me unpack the closet.
B
At last. I'll see what you keep in there. Money. Stacks of money.
D
You will pack this money into those two suitcases, Anna.
B
All right. How about these two small packages?
D
I don't touch them.
B
Huh?
D
I'm never going to be captured alive, Anna. There's enough explosive in this package to kill me and anyone else around. And this is a bottle of vitriolic powder to throw into police officers faces in close quarters. It burns frightfully.
B
I hope you'll never have to make
D
as I told you. It is better to anticipate than to regret. You. You will pack this too, Anna.
B
All right, Professor Horn, you've been wearing a wig.
D
Some fools wait until they're escaping to disguise themselves. I've been disguising myself for 10 years. Now I'll return to what I really look like.
B
They look 10 years younger without that wig.
D
And one thing more. This built up shoe which has made it appear that I limp. Ah, two good legs.
B
So you haven't been lame at all.
D
Professor Horn has now disappeared off the face of the earth. From now on, Anna, you will call me Mr. Harriet. Now let us get on with the packing.
B
What about the body of that man on the floor?
D
Oh, I have everything planned and beautifully planned. The three of us are leaving together. We've been driving some time. Anna, you're getting hungry.
B
Yes, I mean, Mr. Harrod.
D
Here, I have some candy bars in my pocket. Take one.
B
Thank you. Mr. Harris, do you know where this side road goes?
D
Yes, through the most deserted portion of the state.
B
Even so, Cameron's body may be found over there in the bar.
D
Oh, not for weeks if there.
B
Do you think the car's safe?
D
I'll get rid of it as soon as I've hidden my money and securities in these hills against the future.
B
What will we live on meanwhile?
D
And I Can get all the money I want anytime. You forget my constant studies of crime techniques and scientific methods. Even of murder. By accident, by weapons and by poison. Wasn't the candy bar good? Anna, I can't do you.
B
You poisoned me.
D
Of course.
B
Anna.
D
You're the only person in the world who knows what I really look like.
B
How could you expect to go on living?
D
To David Harding Chief United States counter spies Washington from Edwards and Chicago field office counters by LD Cameron vanished while investigating Amberville bank robbery. Local farmer reports talking with Cameron about a Professor Emory Horn of Lipton, Illinois. Horn house checked blood spots on library floor. Horn, housekeeper, Anna Cable and car have also vanished. Advice Chicago from Harding. Peters and I are flying to join you at Professor Horn's house immediately. Allow nothing to be discreet.
B
Her.
D
Here? One of the strangest houses I've ever been in. Yes, and people in the town say it's haunted. Mr. Harding? It is, Edward. With the invisible presence of a fantastically clever man in the entire house. Not one fingerprint except for the woman. Several tradespeople in the town say Horn always wore gloves. Always. Horn spread the story that he once burned his hands very badly in an experiment. Might be true, Peter. Again. It might not. Show his laboratory in the cellar. Yeah, and look at these books. Chemergy and Practical Applications. Calculus and the Theory of Relativity. Works on atomic energy, chemistry, poisons, explosives. It's an extraordinary man to absorb all that, Dave. It's obviously extraordinary. And a genius at covering up. We know one of our own men was murdered here. And there's not a clue. Not even one piece of handwriting. Well, this man may strike again soon. Edward. Yeah. Instruct every counter spy field office throughout the country to report immediately all crimes committed for guilty except where the criminal is definitely known. Yes, sir. Now I'm leaving for a while. What are you up to, dad? Somewhere there's a clue to this man. I want to flounder around a little by myself, see what I can turn up. Doctor Connors. In one of the grocery stores in town. A clerk told me that a year ago Professor Horn wasn't feeling well. And that led me to you. Yes, Mr. Harding. I did treat Professor Horn a year or so ago. Now this is a record of his visit. Mr. Harding. Did he pay you by cash or check? Cash to my nerves. I recall he wore gray do skin gloves throughout his visit here. Did he mention having burned his hand? Yes, but he never removed the gloves in my presence. Did he limp or walk normally? Frankly, Mr. Harding, I didn't notice. But one thing may Interest you? I took some X rays of his stomach. Here, let me show you. These three show all that's important. These, these small darker patches. Ulcer. Peptic ulcers. A severe case, Mr. Harding. A horn is one of those apparently iron nerves. Men who give you outward signs of emotions. They often make the mistake of thinking they have no emotions. Well, actually they do. Their nervousness and emotion seek other outlets. In this case, peptic ulcers caused by a very high strung nervous condition. Doctor, did you give him a prescription? Yes, a special business powder compound. He tried them and they gave him relief. Do you think he's cured of his ulcers yet? Well, I would doubt it very much. Well, the doctor, he'll be buying business powders more or less regularly? I assume so, Mr. Harding. Dr. Connors, I'm very grateful to you. This is the first clue to this cold blooded scientific killer we found. The big question is where will he strike next? Miss Lawrence, file these chemical orders please.
B
But Mr. Johnson, I never handle these local Denver orders, Miss Lawrence. Remember? What is it?
D
What's the matter with all of you? Good day everybody. Why stop working? Don't point those guns at us. Are you the boss here? I. Yes. I like your desk. Move away from it quickly. Yes, all right. Now listen everyone. I have only a few seconds. I've just robbed the finance company office down the hall of $130,000.
B
Well.
D
And there's a big commotion on the ground. Of course the police expect me to leave that way. But instead I'm going to put my two guns on this desk, cover them with this newspaper. Now get this. In a moment the police may come in here. If one of you makes a false move, I shoot. And I am a perfect shot. Does everybody understand? Now, I have a camera here and I'm going to be taking your pictures. Where the tacket. Anybody see anything of a stranger hold up, ma'?
B
Am?
D
Why no, officer. Speak up. Did anyone here see anybody who might be a hold up man? Place down the hall was stuck up, got away. I hope you catch him, Lieutenant. But just a moment. I'm taking some pictures for our sales convention. Would you mind standing there just a second, please. Don't be a fool. No, no, no, no, no.
B
Keep the gun in your hand.
D
Cannon artisan. Thank you, Lieutenant. If anybody sees any suspicious looking stranger, tell the officers who posted my hall. Yes, we certainly will. Okay. I owe you all my thanks. You behaved very well.
B
Why don't you leave us alone?
D
Why, young lady, I couldn't think of it yet. Stand over here, William. I want a photograph of you.
B
Me?
D
That's good. Yes, you are pretty. Smile, can't you? I can. Oh, come now, come now. What a picture of that sincere, honest face. So different from your employers. What do you mean? I noticed the chemical ingredients in that container on the shelf. The set of phenium to present elixir of dichlorosulfate and tritonobar and colloidal suspension. An entirely ineffective combination, my dear fellow. Now, my dear, let's smile.
B
I.
D
Now come, come, come. A lovely girl like you can always smile. That's it. Hold it. Thank you. And now everybody, I'm going out of that door. My guns are in my pockets. Remember, I have photographs of all of you. If any one of you talks to the police, I'll come back and shoot. All clear. Good day and goodbye to you, my dear. Before we go back to counterspy, please listen. Pepsi Cola, it's a spot. Two full glasses that's a lot, lot more value. Lots more death. Why take less when Pepsi best? More and more among fellows and girls, among mothers and dads. You hear that sane and sensible question why take less when Pepsi's best? No budget, no allowance. Ever had a better friend than tangy sparkling Pepsi Cola. Because one big 12 ounce Pepsi bottle gives you two delicious drinks that's twice as much tangy taste. Twice as much delicious Pepsi to go just twice as far. That's why more and more families say why take less when Pepsi is best? Yes, families like yours and mine, families all over America they're all saying why take less when Pepsi is best? Pepsi Cola so delicious and each bottle makes two drinks. It is certainly the cola for the purchaser who thinks the everybody's drinking Pepsi. Just compare it with the rest. So much more and so much finer. Why take less when Pepsi does today, Tomorrow always get America's biggest scolar value. Take home a carton of six big big Pepsi bottles. Insist on Pepsi at the store and say Pepsi at the fountain say Pepsi at the stand, say Pepsi. Whenever you reach for refreshment, remember. Why take less when Pepsi best. And now back to Counter Spy. David Harding and his assistant Harry Peters are in the communications room of a Counter Spy field office in Chicago. Dave, from this report of that big robbery in Denver yesterday, I have a hunch it was Professor Horn. So am I, Peter. The cleverness of the planning, the daring, that camera gag. But no gloves and no limp. I know I can't account for that. And from the description he must have been 10 or 15 years younger. Than Horn. Yes, but it's the tricky method of committing a crime that strikes me hardest. What's our move? Well, send out this new description of him to all police. Encounters by field officers. Also a description to all druggists in Colorado. Instruct them to watch for a stranger who may come in and order a bismuth powder compound. A man similar to this new description. Edwards from the Denver field office to David Hardy, Denver druggist reports that a man answering description of Professor Horn came in to have a business powder compound prescription filled. The the druggist expects the man to return in two hours for the prescription. Harding to Denver. Set up spot surveillance of suspect immediately. But do not alarm him. He may carry explosives or poison for self destruction. I'm joining you by jet plane. Hardly any noise. Dave, jet plane for me from now on. Yes. Remind me to ask for a get Rafel transport model on the next budget. Oh, Denver reporting. Right. Go ahead, Denver. Edwards reporting for the drugstore where Horn just got his medicine. We have a walkie talkie set up with all agents conducting surveillance. You want to be cut in? You bet your life I do. Then I'll have you cut in. Sir, the suspect has turned out of my sight. Our next agent is a sedan one block up. Agent D. Agent D. Is the suspect in your sight?
B
Suspect is walking down the other side of the street from me, taking his time.
D
Oh, he's walking fast now, heading straight up the street.
B
Edward should be near him now in a taxi cab.
D
How about it, Edwards?
B
Come in, Edwards.
D
Edwards reporting again, Mr. Harding. I'm now in a taxi cruising about 100ft behind Horn, who's walking faster now. Maybe for the bus station on the corner. Oh, what is it? A very pretty girl out of the crowd to meet him. He kisses her now. They're heading for one of the buses. Edward, order one of our agents to drive ahead and get on the bus. We'll be with you in Denver in another hour. Yes, Edward, what's the layout? Horn and the girl entered that bungalow there. Place is almost entirely dark. Living room lights are on, but all the blinds isn't on. The place surrounded?
B
Yeah.
D
Set up D. Two men at each post. You want to rush to hound. I want Horn alive. There's no telling what trick he might pull. Let me have your walkie talkie. Yeah. Thanks. Harding to Peters. Peters. Peters. Pull all agents back to setup. See farther from the house. Come over, see me. We have to work out a different plan of attack. It's got to be done.
B
Emily, you play beautifully.
D
Thank you.
B
My Dear, I saw you had a package from the drugstore. You're not sick or any.
D
Oh, no, dear. Not just business powders. They help my stomach.
B
Emily Escilda, I feel very happy with you.
D
I'm glad.
B
Funny, sometimes once in a while you meet someone you feel you've known all your life.
D
It's only been three days, Gildan.
B
I feel as though I've known you all my life. And still I don't know a thing about to accept it. I love you.
D
That's very sweet, Gilda.
B
On second thought, I do know something about you. Something you try to hide from me.
D
And what is that, Gilda?
B
I guess you do it because you really think I'm not very bright.
D
Gilda, what is it?
B
Your brilliant. The books you talk about or remarks about things in the newspapers, on the radio and come in to
D
compare to you, my dear, it is nothing.
B
Emory, there's something else. I know
D
you're not as unobserving as I thought. Gilda.
B
I mean, I think you've almost asked me to marry you and Emily. If you do, I will.
D
Gilda, you're very.
B
What was that?
D
This car crashed into the lamppost right in front of the house.
B
Oh, no.
D
Man seems to have been thrown. Fellas. No, no, no. He was hit by the car. The car's racing way down the street.
B
Those little drivers.
D
We've got to help him away. Kill them.
C
But we can't let him lie there.
D
Very well. I'll go with you.
B
Badly hit it.
D
Face is all bloody. Let's move him up on the line. No, no, no, no. Gilbert, you must never move an injured person.
B
Poor man. All that blood.
D
Let me have a closer look. Bones broken. No shots. Probably really serious. Head contusions and abra. Well, that's funny. I could just see better in this light. You what?
A
Horde.
C
What?
D
That's right.
B
Oh, I knew what you were doing. Come on.
D
I get the handcuff rolling. I got him, Dave. Keep that wild cat off my back. Let me go. You let me go. All right, young woman, we're United States counter spies. Counter spies? You'd better be glad this happened. In another week, you'd have been as dead as Anna Cable, this man's housekeeper. And counters by Agent Cameron.
B
I can't believe it.
D
You were right, Dave. Here's the vial on him, and I'm betting it's explosive. All right, Hotting, I don't know how you found me, but you'll never keep me until you go to the death house. I'll see that you're kept in the safest penitentiary in the country. Han Come on, get going. When your friends drop in, be generous but be thrifty too. Serve plenty of delicious Pepsi Cola. Pepsi's big 12 ounce bottle gives you not just one sparkling glassful, but two. Get a carton of six and serve 12 delicious drinks. Yes, Pepsi is America's biggest troll of value. You get twice the tangy taste, twice the refreshments, twice the Pepsi. So why take less when Pepsi is best? Whenever you reach for refreshments, remember Pepsi Cola Pepsi spots spoonful glasses. That's a lot lot more value, lots more vessels. 5 tastes less when Pepsi's best Tune in every Tuesday and Thursday, same time, same station to Counter Spy.

And escape from an escape proof penitentiary. Be sure to tune in on Thursday day after tomorrow for file number two, Case of a Cold Blooded professor on Counter Spy.

Well, some good stuff in here. In addition to the name cast, I heard Maurice Tarplin doing doubles, most notably as the Faraday like police lieutenant pursuing Professor Horn. Professor Horn himself of course played by Ralph Bell who shows some of his range here. He's often associated with sort of underworld characters who make up series like Boston Blackie, but here playing a far more elegant and refined menace. Professor Horn is a very entertaining villain though there's definitely a theatrical tone to his antics, although it reflects the type of story that we're telling here with this big over the top crime story who's closer to a Batman comic book villain than a Dragnet radio villain in real life. A somewhat less clever but more cautious criminal would probably have gotten further. Harding, as usual, rose to the occasion. And I think if there is a real life, if there's a principle that can be taken from this episode and applied to real life, it's that it is very hard to to hide all distinguishing characteristics. There are small things that slip you up even when you go to the extremes that perhaps Professor Horn did. Imagine a guy who spent 10 years wearing a wig and probably causing himself severe pain by walking with a fake limp and had sweaty hands. So much for that period. So he didn't spread fingerprints. All that and he gets caught because he he needs some powders for his ulcer.

Host: Adam Graham
Episode: Counterspy: The Cold-Blooded Professor, Part One
Original Air Date (Drama): August 30, 1949
Release Date (Podcast): July 4, 2026
This episode features a full-length Golden Age radio drama from the series "Counterspy" entitled "The Cold-Blooded Professor, Part One." The story revolves around the enigmatic and dangerous Professor Horn, a genius inventor suspected of masterminding a highly technical bank robbery. The episode follows Counterspy agents as they attempt to unravel Horn's elaborate crimes and track him across several states, delving into his chilling methods and constantly shifting identity. After the drama, host Adam Graham provides insightful commentary about the performance, villains, and lessons from the tale.
"The Cold-Blooded Professor, Part One" combines classic Golden Age radio suspense with psychological intrigue. It showcases a villain whose brilliance and paranoia are undone by small human vulnerabilities, and demonstrates the charm, tension, and theatrics of vintage detective audio. Adam Graham’s commentary contextualizes the story’s pulp roots, memorable villain, and the enduring lessons about the impossibility of completely eliminating one’s unique traces. Listeners are left eager for Part Two and grateful for a compelling performance and expert radio storytelling.
