Episode Overview

In this episode from the classic radio adventure series "Magic Island," Captain Bradford and Jerry explore a secret tunnel in the mysterious underwater city of Euclidia. They are guided by tips from Elaine Raleigh (formerly known as the Commander), who has recently joined their group. The central theme of this episode is discovery and hope: our heroes find a potential escape route that could lead them to freedom, but face imminent danger as their secret is threatened by the appearance of a Euclidean agent.

Key Discussion Points & Plot Highlights

1. New Addition to the Group (00:30-01:09)

• The party now includes Elaine Raleigh, previously the "Commander," punished by being sent to live with the Gregory group for helping them escape.

  "The girl, whom we have known only as the Commander has been sent to live with our party as a punishment for aiding them to escape from the Magic Island. She's a very lovely and clever young person and will be known from this time on as Elaine Raleigh." – Narrator, 00:30

2. Exploration of the Tunnel (01:09-02:24)

• Jerry and Captain Bradford traverse a secret, narrow hallway, discussing its purpose and their strategy for escape.

• Jerry trusts Elaine's knowledge, which he shares with Captain Bradford.

• Lighthearted banter reveals a budding affection Jerry has for Elaine, and some delicate advice from Captain Bradford about not upsetting Joan.

  "Maybe just as well if you didn't say too much about how nice you think Elaine is, especially when Joan is around." – Captain Bradford, 01:52

3. Strategy for Escape (02:24-03:08)

• The duo speculates about a possible emergency exit, prompted by Captain Bradford's dinnertime theory that clever Euclideans would surely have more than one way out of the city.
• Elaine's information suggests there's a hidden shaft leading close to the surface.

4. The Solvent Plan (03:08-03:48)

• Jerry suggests using Captain Bradford's universal solvent to threaten the city with destruction, using it as leverage to negotiate surrender from the Euclideans.

  "Our only real hope to use my solvent as a threat when we try to capture this place is to find the highest point in the city, suspend a quantity of the solvent there and threaten to release it and destroy the city. That is, unless the Euclideans surrender at our terms." – Captain Bradford, 03:32

5. Discovery of the Steel Door and Airlock (03:48-06:13)

• Jerry and Captain Bradford discover a heavy steel door, which opens downwards due to structural limitations, indicating they're near the top of a mountain.

• Behind the door is a room made of transparent steel, filled with light—an airlock near the surface of the ocean.

  "That room is made of transparent steel and it's mighty near the surface of the water..." – Captain Bradford, 06:22

6. Escape Room Mechanics and Implications (07:03-07:44)

• The room functions as a floating lock: equalizes pressure to allow access to the ocean, similar to locks in the other parts of Euclidia.
• Escape is feasible: they estimate being only 30 feet (about 5 fathoms) below the surface—swimmable in an emergency.

7. Moral Considerations and Plan for the Euclideans (07:44-09:27)

• Discussion shifts to the fate of the Euclideans if the group manages to overpower them.

• Captain Bradford resists the idea of retaliation, suggesting the founding of a scientific foundation rather than imprisonment.

  "After all, Jerry, all they've done is to be just a little too brilliant for the present order of society... While that may be dangerous, well, certainly isn't criminal.” – Captain Bradford, 08:37

8. Unexpected Danger: Visitor in the Airlock (09:39-11:32)

• A shadow passes overhead—the outline of a Euclidean rocket plane whose occupant dives into the water, headed for the airlock.
• Panic follows as Jerry and the Captain must avoid detection—if discovered, their escape route will be compromised.
• The pair hastily exit, narrowly evading the intruder.

Memorable Quotes & Moments

• On Elaine’s New Name:

  "I've called to the commander so long that it's hard to remember to call her anything else. Elaine is sure a swell name." – Jerry, 01:29

• On the Solvent Threat:

  "Our only real hope to use my solvent as a threat when we try to capture this place is to find the highest point in the city, suspend a quantity of the solvent there and threaten to release it..." – Captain Bradford, 03:32

• Surprise at the Escape Room:

  "That room is made of transparent steel and it's mighty near the surface of the water." – Captain Bradford, 06:22

• Hope in Finding a Way Out:

  "If we're only 30 ft below the surface of the water, we could swim out if we had to without getting hurt." – Jerry, 06:45

• Ethical Debate:

  "After all, Jerry, all they've done is to be just a little too brilliant for the present order of society... Well, certainly isn't criminal." – Captain Bradford, 08:37

• Danger Escalates:

[Narrator]

There's an old saying that there's strength in numbers. And this is possibly as true on the Magic island or in Euclidea as it is anywhere else. The Gregory party of four has now grown to five with the addition of the Euclidean girl submarine commander. The girl, whom we have known only as the Commander has been sent to live with our party as a punishment for aiding them to escape from the Magic Island. She's a very lovely and clever young person and will be known from this time on as Elaine Raleigh. In the living quarters set aside for Mrs. Gregory and her loyal friends, Joan and her mother are fitting one of Mrs. Gregory's dresses on Elaine while Jerry and the captain are out trying to get a little more information on their position.

[Jerry]

I know I'm right, Captain Bradford.

[Captain Bradford]

Well, I hope you are, Jerry, but this doesn't look much like it.

[Jerry]

Just the same, I think we should keep walking along this narrow little hallway.

[Captain Bradford]

At least it was built here for some purpose. And the more we learn of this place, the more chance we have of escaping from it.

[Jerry]

I know one thing for sure.

[Captain Bradford]

What's that?

[Jerry]

Nobody can hear us talking in this tunnel.

[Captain Bradford]

How are you so sure of that?

[Jerry]

Well, the commander told me so.

[Captain Bradford]

Elaine.

[Jerry]

Yep, that's right. I've called to the commander so long that it's hard to remember to call her anything else. Elaine is sure a swell name.

[Captain Bradford]

It is a pretty name, Jerry. And Elaine is a very attractive girl.

[Jerry]

You bet she is. I think she's mighty nice.

[Captain Bradford]

Well, I'll agree with you, son. But if you don't mind, I'd like to give you a little advice about her.

[Jerry]

About Elaine?

[Captain Bradford]

Mm, Elaine and all the rest of the ladies.

[Jerry]

Yeah, what is it?

[Captain Bradford]

Well, Jerry, just as one man to another, I'd say that it might be just as well if you didn't say too much about how nice you think Elaine is, especially when Joan is around.

[Jerry]

Oh, sure, I figured that out for myself. Joan gets all steamed up every time I say something nice about the girl.

[Captain Bradford]

Yes, you may find that such things will happen to you from time to time.

[Jerry]

I know that women are all alike, but I guess they can't help acting like that. And they're pretty nice.

[Captain Bradford]

Not bad, Jerry. And if you understand them that well, I'll let you alone to work out your own problems with it.

[Jerry]

Yeah, but Elaine is mighty smart about things in this crazy place. And when she says nobody can hear us in this tunnel, I know it's right.

[Captain Bradford]

Well, at least it's worth taking a chance on. But why do you think she was so insistent that we explore this passageway?

[Jerry]

Well, you started it all by what you said at dinner last night.

[Captain Bradford]

What was that?

[Jerry]

Well, when you said you thought there must be some easier way to get out of this underwater city than taking a submarine out through those locks.

[Captain Bradford]

Well, I naturally figured that anyone as clever as these Euclideans are would have more than one exit. There would always be an emergency outlet someplace.

[Jerry]

That's the idea. And Elaine says there is.

[Captain Bradford]

And she thinks this steel shaft is the answer.

[Jerry]

That's right.

[Captain Bradford]

I wonder. Well, we're going back away from the city now and climbing at the same time. I'd say this was very near that elevator shaft we came down from the island to the underwater city.

[Jerry]

That's what I think. I've got an idea, Tex. Well, it may be crazy, but I wish you'd listen to it.

[Captain Bradford]

Well, right ahead, Jerry. Ideas aren't so plentiful that we can afford to waste any of it.

[Jerry]

Well, that universal solvent of yours, that's the only thing we've got that's better than anything the Euclideans have, isn't it?

[Captain Bradford]

Yes, I expect that's right.

[Jerry]

And the only way you can use that is to have it where you can turn it loose or pour it out or spill it or let it run down on something.

[Captain Bradford]

That's right. Our only real hope to use my solvent as a threat when we try to capture this place is to find the highest point in the city, suspend a quantity of the solvent there and threaten to release it and destroy the city. That is, unless the Euclideans surrender at our terms.

[Jerry]

Okay, that's swell. And that fits right in with what the commander, I mean, Elaine, said.

[Captain Bradford]

Yes, go on.

[Jerry]

Well, she figures that this tunnel we're walking in comes out inside that mountain that the crater of the volcano is in. Only this thing goes right up inside one of the little peaks around the crater and that the opening at the top is only 30 or 40ft below the water.

[Captain Bradford]

Well, if that's true, say, we're as good as off this place right now. We'll have to be sure that nobody else knows what we know.

[Jerry]

What could they do about it?

[Captain Bradford]

Prevent our coming up here for one thing, and close this off for another.

[Jerry]

Yeah, they'd do that, all right. Hey, Tex. Oh, listen to our steps.

[Captain Bradford]

Yeah, we're off that noiseless steel and walking on rock. Good, solid rock, too. Begins to look as if your girlfriend is correct.

[Jerry]

Boy, it sure does. But it looks like there's something here she didn't know about.

[Captain Bradford]

What? Oh, a steel door, eh?

[Jerry]

Mm. And a mighty heavy door from the looks of things.

[Captain Bradford]

Well, now, if we can get this open. Give me a hand here, Jerry.

[Jerry]

Aye, aye, sir.

[Captain Bradford]

I don't say this isn't going to be any too easy.

[Jerry]

No. Must be some way to get it open, though.

[Captain Bradford]

I don't like to make too much noise. Stay up here too long, we might get caught at it. That would spoil all our plans.

[Jerry]

Sure, but. Well, we may not get many chances to come up here either. I think we ought to try getting through there right now.

[Captain Bradford]

Well, your guess as good as mine in Euclidia. Jerry. Come on, we'll try some more.

[Jerry]

This is. It's sure funny. The door looks like it was stuck to the sides all the way around.

[Captain Bradford]

Yes, except on the bottom here. Put your hands flat against the door and we'll try pushing down on it.

[Jerry]

Down.

[Captain Bradford]

Down.

[Jerry]

Okay, skipper, here we go. Hey, it's moving, Tex. It's. It's moving.

[Captain Bradford]

It sure is, son. Look, it's going down. That's the best thing in the world for us.

[Jerry]

Why? Why is it?

[Captain Bradford]

Well, I'd say there's only one reason for a door to open down. There isn't room for it to open up. And that can mean only one thing. There isn't room for it to open up because we're too near the top of this mountain or whatever we're inside of.

[Jerry]

Gee, Tex, look into that room.

[Captain Bradford]

Yes. Not only into the room, but look through the room.

[Jerry]

Come on.

[Captain Bradford]

Wait, wait. Hold it, Jerry. Wait till this door is all the way down into the floor. You might get hurt if you start in there now.

[Jerry]

Okay. Boy, that's something to see, isn't it?

[Captain Bradford]

It certainly is. Look, that room is made of transparent steel and it's mighty near the surface of the water. Why, it must be.

[Jerry]

Yep, the water's light enough that we. You can see all around in the room. How deep could the water be and let in that much light?

[Captain Bradford]

Well, I don't know exactly, but I'd say, oh, not over four or five fathoms, not more.

[Jerry]

Than 30ft?

[Captain Bradford]

Oh, something like that.

[Jerry]

I think she texted. If we're only 30ft below the surface of the water, we could swim out if we had to without getting hurt.

[Captain Bradford]

We could do just that, son. Well, everything seems to be stationary. Come on, let's go on in.

[Jerry]

Gee, this place isn't very big.

[Captain Bradford]

Plenty big enough for an escape chamber. And that's just what it was designed for.

[Jerry]

Well, how do you get out of here?

[Captain Bradford]

I'm trying to figure that out. I think I have how. Now, look. See that valve down there in the corner?

[Jerry]

Huh? Oh, yeah, I get it. Air pressure, right?

[Captain Bradford]

Boy, either air pressure to bring the pressure of this room up to that outside, or to flood this lock with water.

[Jerry]

Be hard to get out of here and into the water at that. That's a long time to hold your breath.

[Captain Bradford]

I don't have any idea that you're supposed to hold your breath while you're getting out of here.

[Jerry]

Well, how else can it be done?

[Captain Bradford]

Looks more to me as if this whole room was a lock. Yeah, a floating lock can be forced up to the surface of the water.

[Jerry]

Looks like the locks they used to get that rocket plane out of that underwater city.

[Captain Bradford]

Exactly. I think when our time comes to escape from Euclidia, this is the way we do it.

[Jerry]

And you can leave some of your sovereign out in that hallway. So we'll eat down through into the city and let the ocean flood in and destroy everything.

[Captain Bradford]

That's it. Except that we'll give the Euclideans a chance to surrender and become good citizens of the world. You know, after all, Jerry, we're here to stop those scientists before they do a lot of harm in our world with their inventions and discoveries. Our business isn't to hurt anyone.

[Jerry]

Well, I guess not, but they wouldn't worry about hurting anyone else.

[Captain Bradford]

Well, do you know of anyone they've hurt?

[Jerry]

No. Yeah, how about that old sailor who got the first radio message off to us?

[Captain Bradford]

He wasn't hurt. He's alive and well. A prisoner like the rest of us.

[Jerry]

Maybe you're right. But will these Euclideans behave if we do capture them and take them home?

[Captain Bradford]

We'll put them where they'll have to.

[Jerry]

In jail, you mean?

[Captain Bradford]

No, I don't think so. You know, I doubt very much if it's possible to prove anything criminal against them. At least nothing serious enough to keep them in a prison for life. After all, Jerry, all they've done is to be just a little too brilliant for the present order of society. While that may be dangerous, well, certainly isn't criminal.

[Jerry]

But if we can't put them in prison, where can we put them?

[Captain Bradford]

Well, Mrs. Gregory has money, Jerry. Almost unlimited money. Many of her friends are equally fortunate. I'm sure Pat would lead a movement to form a syndicate, establish a scientific foundation for these people. There they would be allowed to carry on their work, but they'd also be watched to see that anything they developed

[Jerry]

would only be used for good sounds. Okay, but it sure cost a lot of money and plenty of trouble.

[Captain Bradford]

It's the only answer I can think of.

[Jerry]

Well, I hope they refuse to surrender and we can turn this water in on the whole bunch of them.

[Captain Bradford]

Now, Jerry, you wouldn't do that.

[Jerry]

Well, maybe I wouldn't want to do that to the animals they've got down there. But I don't feel very bad about anything happening to the Euclideans.

[Captain Bradford]

Why, Jerry, they're human just the same as we are. They're entitled to fair treatment.

[Jerry]

Yeah, only. Hey, Tex, look.

[Captain Bradford]

Yeah, I see it, Jerry.

[Jerry]

Shadow on the water above us.

[Captain Bradford]

Looks like the shadow of a submarine.

[Jerry]

No, it's one of those rocket planes shaped like a submarine.

[Captain Bradford]

How can you tell?

[Jerry]

Well, see the shadows of those little bumps on the sides where the wings don't quite fold into the ship?

[Captain Bradford]

Say, you're right. It is one of the Euclidean rocket planes. It's just drifting on the surface of the water.

[Jerry]

Well, it's going to be right over us in a minute.

[Captain Bradford]

The shape of that shadow is changing. There's a bulge on one side of it.

[Jerry]

Looks almost like somebody was getting out of it and into the water.

[Captain Bradford]

That's just what's happening now. Look, that fellow's feet are touching the water.

[Jerry]

Yep, and we're mighty close to the surface. I'll bet it is over 20ft.

[Captain Bradford]

Near 30, I think. But the water's perfectly clear. Jerry. That man is coming down into the water and he's coming right for this transparent steel lock.

[Jerry]

Hey, let's get out of here.

[Captain Bradford]

Wait, wait. We can step outside the door into the hallway and still see him. I want to watch how this is.

[Jerry]

But if he sees us in here, then our chance of using this place for an escapes are all gone.

[Captain Bradford]

Oh, now look. We'll step backward to the door and start to shut it when it's nearly up to the top. We can safely watch over it and close it quickly when he's near enough to see us.

[Jerry]

Okay, but we'd better get busy.

[Captain Bradford]

Look, Jerry, man has on heavy shoes like a diver, but no diving suit.

[Jerry]

Well, he's got a little thing like A helmet on though, right?

[Captain Bradford]

Just something to allow him to breathe for the few seconds it takes him to get into this lock.

[Jerry]

He's right beside the lock now. But he's turned sideways, so I guess he can't see us.

[Captain Bradford]

Look, he's reaching down to turn something. It's a valve. Just what I thought. This is a lock and he'll fill it with water before coming into it.

[Jerry]

But how can he get the water out of it when he wants to come through this door?

[Captain Bradford]

Probably pump it out with that valve we saw in here.

[Jerry]

Hey, he's letting in the water.

[Captain Bradford]

He's liable to turn around any minute. Here, give me a hand here, Jerry, we'll shut the store quickly.

[Jerry]

Aye, aye, sir.

[Captain Bradford]

Now come on, Sam, let's get away from here quick.

[Jerry]

I'll say. Oh, boy. What we know about this place now

[Captain Bradford]

sure looks encouraging, Jerry. But we'll have to be mighty careful about discussing it with the others.

[Jerry]

But we'll have to tell Joan, their mother and the girl Commander, I mean Elaine.

[Captain Bradford]

We'll tell them all right, but let's be careful. We're as good as out of you, Clydea, right now.

[Jerry]

That's what you think.

[Captain Bradford]

What's up, kid?

[Jerry]

Well, look behind you through the transparent wall of that steel lock we just came out of. Huh, That's a funny one.

[Captain Bradford]

Yes, that fella took off his helmet and stored away in that little cabinet. But he isn't coming out this door.

[Jerry]

Well, he's sure not going to try going back up through that water without a helmet.

[Captain Bradford]

Get out of here quick, Joe. He's coming his way.

[Jerry]

Blame these transparent steel walls. You can't tell when you're through something.

[Captain Bradford]

He's coming down. There's no doubt of it.

[Jerry]

And I'm not sure we can find a way out of here.

[Captain Bradford]

There aren't any turns in this corridor.

[Jerry]

You mean there weren't any turns in it when we came up here. No telling what's happened to it since then.

[Captain Bradford]

Come on, step on it. Jerry. That door is opening behind us.

[Jerry]

If we can't get around the turn in this tunnel before that fellow sees us, we'll never get a chance to see this place for an escape.
