 The K-7 form a United States secret agent who operated in 22 countries on land on sea and in the air brings you a story of today. We take you to secret agent K-7's headquarters. This is K-7 speaking. Send in special agent M for assignment. Special agent M reporting for duty. Agent M, a few weeks ago the notorious spy, Manuel Gornhoff, entered this country. He came from the Orient. Secret service men traced him to this naval base, but here his trail was lost. I think you are familiar with his background. However, here are some additional facts from my personal records. Study them. I want you to get Gornhoff. That's all. Keep me informed. Gornhoff's appearance at the naval base was not accidental. At the very moment K-7 was talking to agent M, the master of freelance spy, faced an oriental whose bearing was that of a military or naval officer. Everything is in redness. I located it in abandoned warehouse and vented yesterday afternoon. You can bring in your cargo whenever you are ready. Good. We will act tonight. The weather is what we have waited for. How about the Coast Guard? It has been arranged to lead them to other parts. Let us take care of everything, don't you? It is often wise to be cautious. You have done your work well, Gornhoff. Now I will give you your instructions for tonight. A small fishing boat will enter the harbor about midnight. The drums of chemical will be aboard. And how are you going to get them ashore? You will supervise that. Several small boats, which belong to my people, will be put at your disposal. They will report to you at the old warehouse. At midnight, send them out to me offshore. Each boat will return with 10 drums. Your job will be to see that the drums are carefully stored. That will not be difficult. What do you want me to do after the chemical is ashore? You will remain here and keep out of sight until we are ready to strike. That is all. I see. When are you going to let me know what this is about? I am not used to working in the dark. The government usually gives me full information before I begin. Yes, but this time I have waited until now. Until now? You have never worked with me before. I was not sure you would be willing to continue if you knew what we planned. Go on. This country cannot strike against us except through its navy. We are going to destroy the fleet. Destroy the fleet? But that is impossible. I think you will see differently when I explain. These drums we bring ashore tonight contain a new chemical. When combined with salt water, our secret chemical will eat its way through the thickest steel within a few hours. Do you mean it will eat the bottom out of a ship? Exactly, my friend. Our chemists have worked on the formula for many years. Next week the fleet returns here. As soon as all the battleships are at anchor, you will pour the drums of chemicals into the water of the harbor. Within a few hours the fleet will be useless. The battleships will sink to the bottom of the bay, their bottoms eaten out. Sachi, are you telling me the truth? I am not accustomed to being doubted. Chemical that will eat the bottom out of a battleship and combine with sea waterway. And your country can rule the world. That is our destiny. Now I leave you. Be at the warehouse at midnight. New secret chemical that one poured into sea water would eat through the steel bottom of a battleship. The plot was a desperate one. The fleet was threatened. That afternoon Yvonne studied the records of Grunhoff's career as a freelance espionage agent. As she went over the files, Agent M worked different wavelengths with a shortwave radio receiver. I've finished, M. Oh wait Yvonne, don't talk now. I'm taking this message down. What did you say? I finished reading Case 7's personal records on Grunhoff. I don't see where we're going to start this case. We've already started. What do you mean, M? I had a hunch and played it, Yvonne. That's why I've been listening on different shortwave bands. That message you just heard may give us the lead we're looking for. You think it has a connection with Grunhoff? I don't know. The message came from a nearby and powerful station. What did it say? That's what we're going to find out. It's entirely in code. And the code that I don't know. Then how are you... We're going over to Intelligence Headquarters and talk to L6. He's the greatest code authority in the world. I think he'll be able to set this one. Are you ready? Yes. Then let's get started. Unless I'm mistaken, Yvonne, this case is going to bring us face to face with the rising sun. That night, a small fishing boat without running lights dropped anchor far out in the harbor. Immediately guarded lights flashed around the old warehouse. The drums of the mysterious new chemical began going ashore. Yvonne watched from behind a pillar of a rotting whore. Five small boats have come in. I've got to signal M. He may not have found out that the boats are there in the darkness. I told him not to use my flashlight, I had to, but I've got to signal him. Three long flashes of a signal to come ashore. Stand where you are. If you attempt to move, I will shoot. Good. Who are you? That is a question I would like you to answer. What are you doing here? I... I cannot walk. I often come down here. I don't believe you. What were you doing with that flashlight? Well, I... Well, I heard a boat out there in the darkness. I thought perhaps something was lost. I couldn't see any lights and, well, it might mean something was in trouble. You are the one who is in trouble. Don't come any nearer. I'm on the edge of the dock. You are coming with me. Don't try that. Let's go. There was only a splash as the body disappeared below the surface of the dark water. A few minutes later, the oriental who had talked with Gronhoff came ashore with the last boatload of the drums. That is all. You will return to your home. Yes, master. I will stay here and return to the city with Gronhoff and suck the others to go back to their homes. Some have already gone. I will tell the others where is Gronhoff. You'll find him across the dock. Good. That is all. Go. Don't let them to call out. Who are you? What are you doing here? I'm Special Agent M. I place you under arrest as a spy. You have made a mistake. I don't think so. I intercepted your radio message this afternoon. I heard you order a fishing boat to come ashore with some chemical tonight. I think you've got a few things to explain to our authorities. Now turn around and I'll get your gun. Don't try anything. You will regret this. Perhaps. But I'm going to have the satisfaction of hearing you explain what is in the drums you brought ashore and why you smuggled them in. Now. Walk straight ahead. If all of you attempt to move up. Yvonne. M. I couldn't see you in the darkness. Who is this man? Unless I'm mistaken, he's the man who hired Gronhoff, Yvonne. He came ashore with the last load of drums. He's under arrest. M. I know what's in those drums. I heard two of the men talking. It's a chemical to be poured into the water of this harbor. And when it's combined with sea water, it becomes strong enough to eat the bottom out of every battleship anchored here. I've heard rumors of such a chemical. Now here, keep this man covered. I've got to find Gronhoff. You won't have to, M. He tried to seize me and in the darkness I hit him over the head with my gun. He fell into the bay. That leaves just one thing more for us to do. Then we'll take this officer to the naval authority. Where are you going? I'm going to destroy the warehouse. Officially I wouldn't dare. I'm going to act unofficially and burn it to the ground. The chemicals it contains are too dangerous as weapons of war. Sea power is of extreme importance today and there have been many plots against the fleet of the great democracies. However, the democracies still rule the seas and champion the cause of peace. Listen for my next story. This is K-7 speaking.
