Listen to Herbert Marshall as the Man Called X. Wherever there is mystery, adventure, intrigue in all the strange and dangerous places of the world. There you will find the man called X. A century and a half ago, a dream was born in the mind of a man. A dream of a country where life, liberty and the pursuit of happiness were the birthright of every citizen. And on the day he was elected as his country's first president, he knew that his dream had come true. The man, Simon Bolivar. The country, Venezuela. Now, in the dining room of the Hotel Venita in Caracas, capital of Venezuela, there sits another man with a dream. His name is Louis Dalla Costa. And he's telling of his hopes and his aspirations to a longtime friend.
C
Just think about it, Ken. Thousands of my people, their villages isolated for centuries, will at last be able to enjoy the benefits of modern civilization. Schools, hospitals, decent homes.
D
It's a wonderful dream, Louis.
C
But it's to be a reality, too, when we have completed the Bolivar Waterway.
D
Bolivar Waterway? Oh, you mean your old idea of opening the interior rivers to navigation?
C
See, by building a waterway almost 200 miles long is being financed by American interests who would profit handsomely from the iron ore mountains of the inferior. But someone, some country perhaps can, does not wish that ore to reach your hungry steel mills.
D
Having trouble on the construction job.
C
Breakdown of equipment, vital materials lost or stolen. A dam has suddenly collapsed.
E
They.
C
Ken, tell me, does the name Kolenda mean anything to you?
D
Colenda? Sure. Freelance international crook specializing in sabotage. Is Kolenda behind your trouble?
C
I have reason to think so, Ken. That's why I come to you. And the first thing that you should know.
D
All right, Bruce. I'll see what I can do.
F
But, Mr. Chief, be reasonable. You got to tell me where I can find Mr. Rex Dale Schmidt.
B
The answer is no.
F
But he needs my invaluable services. He'll be lost without me.
G
And besides all that, you're broke.
E
Yes?
F
No, no, no. What's that got to do with it?
B
Hagon, this is one time you're not gonna get in Ken's hair. You're not gonna foul up the assignment he's working on, and you're not gonna chisel him out of any more slight consideration, mister. Now get out of my office. Get out.
F
Okay, okay, okay. You think after all the years we've worked together, doing things for me.
D
Hello?
F
Hello?
D
Chief.
B
Oh, Ken, Glad to hear you. Glad to hear from you. Hard things, wherever you are.
D
What are you so happy about?
B
I just had a delightful little interview with Pagan Zellschmidt. Haven't enjoyed anything so much in years. But what can I do for you, Ken?
D
Send Pagan down here to meet me.
B
Sure. Be glad to. I'll see the.
C
What?
D
I need him in Venezuela right away.
B
Ken, you can't do that to me. What do you want him for?
D
Five years ago, he was mixed up with a sabotage ring in Lisbon. Somebody named Colander was at the head of it. But listen, Colander's busy down here on the Boulevard Waterway. I need Pagon to make a positive identification.
B
But, Ken.
D
I'll talk to you later. Chiefs along. But.
B
But.
E
I. I beg your pardon, sir. I beg your pardon. Might I trouble you for a moment?
F
A moment?
D
Sure. What can I do for you?
E
I'm lost without my dictionary. Positively lost.
H
English?
E
Spanish. Oh, it was Spanish English, that is. And I must find Maria Luisa. Yes, I positively must.
D
Maria Luisa.
E
A boat, sir. Riverboat. Going up the Orinoco to the Bolivar Waterway. Yes, the Bolivar. Oh, by the way, I'm Professor Harkness. Artemides Harkness is the waterway.
D
My name's Ken Thurston, Professor. And the boat you're looking for is right over there, eh?
E
Oh, it is? Well, thank you, Mr. Thurston. Thank you very much.
D
What's your interest in the waterway, Professor?
E
Why, the Lalia Paparata, of course.
G
Yes.
H
That is, you know.
F
Yes.
E
Saprophytic.
D
You're looking for rare orchids?
E
Well, that's what I said, isn't that? Yes, I'm a botanist, you know. Yes, a botanist. Many rare specimens in the interior. Very many. Wonderful opportunity to travel by water Boulevard. Waterway, you know.
G
Yes.
D
Here's the Maria Luisa.
F
Maria.
E
Oh, yes, yes. Thank you.
H
Thank you. You're looking for something, gents?
D
My name is Ken Thurston. This is Professor Harkness. We're looking for the skipper of this boat.
H
You found her, mister. So? Why?
E
Well, I have passage. There's a ticket somewhere. I purchased it, you know.
H
Ah, yeah, yeah, Professor, I already got you booked. It's this Thurston I want to know about. You interested in going upriver to the waterway?
D
That's right.
H
It'll be 50 bucks American, cash in advance.
D
Sure. Regret. There you are.
H
Okay, we're shoving off in 10 minutes. Stow your duffel below.
C
Duffel?
D
Luggage, Professor?
E
Oh, yes, yes, you can.
G
Luggage.
D
Oh, of course.
E
Yes.
H
All right, Thurston, what's the Pitch? What's with you in the waterway?
D
Well, that's pretty much my business, isn't it?
H
Not the way I figure.
D
Just how do you figure?
H
You're traveling light. You're no construction stiff. You're going up to the waterway. And that to me adds up to a snoop job of some kind. That means I got something you need.
D
Like what?
H
Insurance.
D
What kind?
H
The kind Louis Delicosta needed and didn't have.
D
News travels pretty fast around here, doesn't it?
H
We were talking about an insurance deal.
D
I suppose I think it over.
E
Sure.
H
Take your time. You'll be okay till we hit the construction job.
D
And after that?
H
You name it, pal.
D
Yeah, speaking of names, Betty Corcoran. Corcoran?
H
That's right. What did you think it was going to be? Glenda? Okay, Thurston. Here's the waterway construction job. You buying that insurance?
D
The answer is no, Ms. Corcoran.
H
You're a sucker. Why, this job's poison for people on the wrong side of the fence. But there's plenty of dough to be made on the right side.
D
Your side. Colinda's.
H
You gotta pay for what I know, mister. And if you don't, first the construction office.
D
Yeah. Let's have that gun. Let's have it. That's better. Now, what's going on here?
G
And just what business is it of yours, senor?
D
Let's say I'm allergic to murder. Now suppose you start talking.
G
I suppose you go to the devil, Senor Miguel.
C
It's possible this American represents the financial interest behind the Bolivar Waterway. Am I correct, senor?
D
You might call it that.
G
Sie.
C
I am Manuel Florio, government inspector on the waterway. My hot headed friend here is Jose Martinez, engineer in charge of the construction.
H
Yeah, and this is Ken Thurston. Okay, now let's hear what the fireworks were about.
C
It's really quite simple. My friend Martinez is about to blast a passageway for the new riverbed. I expressed the opinion that he was using an excessive amount of dynamite. Enough to bring the hillside down upon the cut that we have made. By way of answer, he reached for his gun.
H
Wait.
G
You fizzy line, Martinez.
D
The only thing that's important now is that waterway. Let's go down, take a look at the dynamite charges. I'll be able to tell soon enough.
B
Oh.
F
What did you miss?
G
Your blast was set up too soon.
C
See, with your heavy charge of dynamite, Martinez. And look here, look. You can see what happened to the canal that was already built, senor.
D
Completely buried.
H
Yeah, a couple of million bucks worth of waterway shot. Just like that. Too bad you weren't carrying any insurance, isn't it, Mr. Thurston?
B
We'll return to the Man Called X in just a moment. Answer the call. Answer the call. For volunteers to help during the Red Cross Fun drive. Now is the time to lend a hand to the organization which is always ready with help wherever and whenever it is needed. As a fund drive volunteer, you help to save the life of a wounded soldier through the Red Cross Blood center. You offer comfort to a crying child, a grieving mother, a good friend, good neighbor, a citizen to be proud of. That's a Red Cross Fun Campaign volunteer. Call your nearest Red Cross office and help the Red Cross give help to the helpless, hope to the hopeless as a Red Cross Fun Campaign volunteer. And now, act 2 of the man called x. Starring herbert marshall. With leon velasco as pagan zellschmidt. Louis Dalla Costa's dream was about to be realized. A dream of a giant waterway carrying precious iron ore from the interior of Venezuela for America's hungry steel mills and bringing schools, hospitals, homes to thousands of his people in return. And then sabotage struck the waterway. Delacasta was murdered. And now a premature dynamite explosion has just buried an already completed canal.
H
Yeah, Thurston, that's what this job should have had. All right. A little insurance to take. Take care of things like that powder bl.
G
You are wrong, Senorita Corcoran. What this waterway needs is guns to protect it from its enemy.
C
Or perhaps Martinez needs engineers who will listen to advice regarding an excessive amount of dynamite.
D
That kind of talk won't get us anywhere, Florio. Martinez. The damage is done. Those you check, see how bad it is. See what could be done to rectify it.
G
I already know the answer to that, senor. But you have taken my gun away from me.
C
Oh, that's too bad. I'm afraid our construction engineer is too hot headed and impulsive for his own good.
H
Cicin. She's got blood in his eye when he looks at you, Florio.
D
Maybe he doesn't like the idea of being blamed for that premature blast. Maybe he figures somebody else is responsible.
C
And just who would that somebody else be, Senor Person?
D
It's your question. Got an answer?
C
If you will excuse me, I shall check upon the damage with Martinez. But a word of advice first, if.
D
You do not mind. No, no, go right ahead.
C
The construction of a waterway such as this is best left in the hands of experts. Amateurs are prone to run into accidents. Possibly even better ones.
G
Hasta.
F
Well, hello. Is this the water reconstruction outfit?
D
Pagan.
H
That's right.
F
Pagan. Zellschmidt, I'd like to talk to. Oh. Oh, hello, Mr. Thurston. How's everything going there with it waterways and bolivars and stuff?
D
What the devil's been keeping you? Why aren't you here?
F
Sunburned?
D
Sunburn?
F
Sure. Boy, that sun's plenty hot here on the beaches.
D
There are no beaches in Caracas.
F
That's right. But you ought to see this one here in Miami.
D
Miami?
F
Well, I had a little trouble in the plane, you understand. And by the time I got through explaining to those police characters about that poor lonely little steward as well, the plane for him in Israel had already left.
D
He gone. So hopefully, if you don't get another plane out of there right away.
F
Oh, don't worry about the thing, Mr. X. I'll be there in plenty of time to put the fingers on that calendar. Characters for a slight consideration course.
G
Swing the transes over onto the other.
H
Side of the hill.
G
See, that is correct around your lines over there.
D
Looks like you're shifting the base of operations, Martinez. Mind telling me why?
G
Senor Thorsten, the accident last night was not as damaging as we feared. It will be possible to reroute the channels and a simple blasting operation will do it.
D
Like the last one, senor, I agree.
G
That the blast was much greater than it should have been. But the extra dynamite was not placed there by me, nor did it come from our powder house.
D
What makes you think that?
G
Because there is a sulfur mine operating back in those hills. Early this morning, I found over 50 empty dynamite boxes near that mine. They still had yellow sulfur dust on them.
D
Anything else?
G
Only this. I understand. The controlling interest in that sulfur mine is held by Senorita Perry Corcoran.
E
Oh, miss. Mr. Thurston, just one moment, please. Just one moment. Ah, well, I thought I'd never find you.
H
Never.
D
Oh, Professor. What's on your mind?
E
Ms. Corcoran, that is. She asked me to give you a message. Just a message.
D
What is it?
E
Well, she would like to see you, I believe.
B
Believe?
F
It was about.
E
Oh, those boxes. Oh, my, there are a lot of them. What are they, Mr. Thurston?
D
Empty dynamite cases.
E
Dynamite? Are they real? Well, well, imagine that. Empty dynamite.
G
Well, well.
D
The message, professor, from Betty Cochrane.
E
Oh, yes, yes, Ms. Cochrane. Well, she wanted to see you about dynamite and a man. A man named. Oh, dear, what was that name again?
D
Colinda.
E
Yes, yes, yes, that's Kolenda. She's waiting for you now, Mr. Thurston. At the Sulphur mine.
C
Betty.
D
Betty Corcoran. Are you in here? Funny, I thought I saw something moving. Well, Betty, is that you?
B
Over.
C
Are you feeling better now, senor?
D
What? Who? Oh, Florio.
C
See? That's quite correct.
D
What are you doing here? What, do you make a habit of dropping the sulfur minds at odd hours?
C
Professor Harkness informed me as to where I might find you.
D
Before or after I came into this mine.
C
I'm not quite certain I understand your meaning.
D
Somebody hit me, Florio. Right now it looks like a toss up between you and Betty Cochrane.
C
It was neither of us.
D
What makes you so sure?
C
Because when I entered the mind, you were already unconscious, and I am certain that you cannot. Dulce and you read a Corkyn, Alabama.
D
Why not?
C
Here, I show you.
G
There.
E
Oh, see?
C
As you can see, she's quite dead.
G
So the Senorita Corcoran is dead?
D
That's right. Martinez. Murdered.
G
And I suppose the work on the Bolivar Waterway will come to a halt until our murder is solved.
C
See, Martinez, I have placed a telephone call to the authorities in Caracas. Meanwhile, all work on the project will cease.
G
Of course, you could not afford to wait another 24 hours, for then we will be ready to blast open the new riverbed and the Bolivar Waterway will be finished.
D
I'll get it.
F
Well, hello, Mr. Thurston? This is Pagan Zellschmidt. Guess who.
D
Where are you calling from now?
E
That's right, Mr. Thurston.
F
I'm calling all right, from Trinidad.
D
Trinidad?
F
Well, the airplane lost a couple of wheels or something and I got all grounded up here.
H
Mario Pagan, darling. Carmen Goish is to die.
F
Oh, sure, baby.
D
Sure, sure. Pagan, you've got just 24 hours to get get up here. And so help me, if you're even one second late.
F
Mr. Thon, if there's one thing you can always depend on, you can always depend on a.
D
Keeping busy, Martinez.
G
Oh, Senor Thurston, Looks like you're figuring.
D
On setting off a dynamite blast all by yourself.
G
The 24 hours is up, and I intend to see that the Bolivar Waterway is completed tonight.
D
Pretty risky, isn't it?
G
What risk, senor? I detonate the explosive and the river rushes into its new channel. Then there will be nothing that Florio can do.
D
Yeah, if it works out.
G
Why should it not?
D
I just found 30 more dynamite cases in the sulphur mine lying over the hill empty.
G
So we were about to have a.
C
Repeat performance of the last explosion.
D
Senorio. It's set to go off 10 minutes from now. Only this time without the extra dynamite.
G
I tell you, I know nothing about that sulfur mine. Dynamite?
E
Yes. But I saw the empty boxes too, Mr. Martinez. Mr. Thurston showed them to me. So I'm a witness? Yes, I'm a witness. For the life of me, I do not know what this is all about, Mr. Thurston.
D
It's simple, Professor. Man named Donna Costa had a dream about this waterway. It would bring a new way of life to the people in the Venezuelan hills. And iron ore for steel mules in the United States.
E
But what does all this to do with sulfur mines and dynamite?
D
Somebody's been sabotaging the waterway to keep that iron ore from leaving here. And using the sulfur mined dynamite to do it. A man by the name of Colenda.
G
Colenda?
E
Oh, yes, yes, of course. The man, Ms. Corcoran. The one she. Well, before she was happy. Yes, Colinda.
C
And just who is this Colenda, senor?
D
Have you. Have you got a silver coin, Florio? A bolivar or peso?
G
Why?
E
See, see, I have one here.
D
Thanks. What about you, Martinez and Professor Harkness?
G
See if you wish.
E
Here you are, Mr. Thurston. But I would like it back. My pension. It's not very large, you know. Not very large.
D
You'll get it back, Professor. These coins are all I need to. Tell me which one of you is Colenda.
G
What do you mean?
D
Colendra used dynamite from that sulfur mine. There was plenty of yellow sulfur dust on the empty boxes. Plenty more in the mine itself. He must have been covered with the stuff by the time he got through.
G
That means nothing. There is no sulfur dust on any of us. It can easily be washed out of clothing and off the skin.
D
That is right, Martinez. But it can't be washed off. Silver.
G
Silver.
E
Of course.
C
The chemical action of silver would leave a black coating. It would be first. And look, look. One of those coins, Joe.
D
This one. Black. Yeah, Glinda gave it to me. Didn't you, Professor Harkness?
F
Hello, Mr. Thurston. Hagon, you don't have to worry about the thing.
D
Get away from there, you idiot.
F
But this character I'm standing between is Calendar.
D
He's the one on the.
G
Oh, thank you, salesman, for getting in front of me.
F
Adios, settlement.
E
What's going on here anyways? What happened?
C
Get away from that door.
H
Nice.
G
Lock the window, Florio. There he goes into the speedboat at the dock.
C
Oh, it's no use, Martinez. He's getting away.
D
I don't think so, Florio.
C
But you can see for yourself. It's already going down river. Approaching the new channel where the new waterway will be.
E
Sephiroth. In that boat Colinda. Where they were, there's nothing. Nothing but.
D
Yeah, that's right.
E
Pagan. Hey, that noise. What is it now?
D
You might call it the beginning of the Bolivar Waterway. But somehow I'd like to think of it as a dream coming true.
B
And now, here again is our star, Mr. Herbert Marshall.
D
Thanks for being with us. And my thanks to Gloria Blondell, Will Wright, Paul Richards, Howard McNear and Tony Barrett. Next week, the icy wasteland of Alaska, where a deserted weather station holds the answers to a missing top secret weapon, a man who dies twice and one of the most unmitigated scoundrels whoever. Yes, that's right. That reminds me. Leon Balaska will be along as usual as Pagon Zelschmitt. So join us, won't you? When next I return as the Man Called X. Good night.

Series: The Man Called X
Date: November 21, 2025
Host: RelicRadio.com
Setting: Venezuela, focusing on the construction of the Bolivar Waterway
This episode of The Man Called X—titled "A Ton of Dynamite"—takes listeners to the jungles of Venezuela, where Ken Thurston (the Man Called X) investigates sabotage at the construction site of the Bolivar Waterway. The waterway, a project meant to bring prosperity and modernization to the region and supply America with essential iron ore, is being threatened by a series of deadly accidents and mysterious setbacks. As Ken searches for the perpetrator—believed to be the elusive saboteur Kolenda—he navigates a web of deception, murder, and shifting alliances among the international cast of characters.
| Timestamp | Segment | |-----------|------------------------------------------------------| | 01:56 | Dalla Costa describes the waterway’s transformative aims | | 02:55 | Kolenda identified as prime suspect in sabotage | | 09:37 | Discovery of sabotaged canal after a blast | | 13:24 | Pagan’s comic misadventure revealed (Miami instead of Caracas) | | 14:42 | Martinez mentions sulfur mine dynamite connection | | 17:32 | Betty Corcoran’s body found in the sulfur mine | | 21:20 | Coin test reveals Harkness as Kolenda | | 23:08 | Successful completion of the Bolivar Waterway and final blast |
The episode maintains a classic Old Time Radio blend of intrigue, suspense, and occasional comic relief. Herbert Marshall’s Ken Thurston is dry, determined, and methodical; supporting characters bring a mix of earnestness, mistrust, and comic bumbling.
This episode stands out for its clever blend of international intrigue, scientific deduction, and thrilling detective work, all set amid the atmospheric backdrop of Venezuela’s riverfront jungles. The themes of progress battling corruption—and the high stakes of Cold War-era industrial projects—echo through the drama, making A Ton of Dynamite a classic adventure for fans of suspenseful storytelling.
