 America's number one adventurer K7 form United States secret agent who operated in 22 countries on land on sea and in the air brings you a story of today. Here is K7. Ladies and gentlemen, sabotage is dangerous to the peace of a nation, for through sabotage defenses are often weakened. In different words I have made that statement before and I shall probably make it many times in the future. It is a danger that must be kept constantly in mind and it must be constantly guarded against. It is a different story of sabotage which John Holbrook introduces now. Thank you K7. Recently a new high speed heavy bomber was tested. Special agent M was on the field and watched those tests. The reports by radio made them as real as if he'd been in the plane. Ground speed 230 miles per hour. Airspeed 260 miles per hour. Airspeed 260 miles per hour. Wind velocity 30 miles. Wind velocity 30 miles. Altitude 10,000 feet. Altitude 10,000 feet. Right motor number two out. Right motor number two out. Left motor number three missing. Left motor number three missing. Altitude 8,000 feet. Altitude 8,000 feet. Left motor number three out. Left motor number three out. Right motor number one missing. Right motor number one missing. Altitude 6,000. Altitude 6,000. Altitude 5,000. All motors out. All motors, out! Altitude 3,000! Altitude 3,000! Altitude 2,000! Altitude 2,000! 1,000! 1,000! Impossible to pull off! To take trash positions! All on the field. All of you heard the radio report. This court of inquiry has heard other details of construction, of the flying qualifications of the officers in charge. You have all examined the wreckage. However, one man, Colonel Guimond, of Special Agent M, has made a detailed study. Colonel Guimond, what are your findings? Vama had no structural defects, gentlemen. Then this court of inquiry has completed its study. However, before adjourning, I would like an expression of opinion from Special Agent M. Special Agent M. What in your opinion caused the destruction of Bomba 2L 5W? Sabotage. I base that belief on the fact that all motors fail to approximately the same time. The Court of Inquiry was examining the evidence in an attempt to establish the cause of the crash. Ivan, Special Agent M's assistant, was making other investigations under M's instructions. You have finished, Madam Hotel? Yes. I have the fingerprints and history of each of your drivers. I want to check them against your employment records. You have those records here? Yes, of course. They are in this file. I will read the name. Answer me, giving you a birth and nationality. Ready? Leo Piron. A citizen born 1903. Carl Stuller. A citizen born 1903. Jean Martino. Naturalized citizen born in Cuba year 1900. Leroy Duclon. Naturalized citizen born 1903. A few hours later, M and Ivan compared notes in M's laboratory. Did you check the fingerprints, Ivan? Yes. None of the men had the criminal record. Yes, I expected you to find that. What were their reactions when you took the prints? Most of the men took it as a joke. Only one mentioned the crash. And he seemed nervous, M, terribly nervous. Exactly. What were his words? He asked me if they had discovered why the bomber crashed yesterday. I told him that so far I hadn't had time to read the story. Then he wanted to know why he was being fingerprinted. Was that man employee 217? Wait until I look in the back of these prints. Yes, M. Then we've got him, Ivan. You'll place him under arrest and question him? We allotted him to be at the field tomorrow morning. A second bomber is going to be tested. This evening's newspapers will carry the story. The plane is to go up for a six-hour test. It's to be serviced by the same men who serviced the first plane. Aren't you taking a terrible chance, M? You say you're sure you know how the bomber was sabotaged? I'm taking every precaution. Now, here's my plan. The newspapers will be on the street within an hour. I'm going to pick up this man, number 217, and follow him from the time the newspapers come on the street until tomorrow morning. Then I'll know whether I'm right by then. And he'll give himself away if he's guilty. If my trap works, yes. You see, Ivan, the papers will announce that arrest will be made on the field tomorrow morning. Now I'm going to leave you. Meet me in hangar number one tomorrow morning for instructions. On the evening, M picked up the trail of the man he suspected. He watched him buy a newspaper, read it hurriedly, then enter a telephone booth. M entered the adjoining booth. Hello? Hello, Grulla. Have you seen the newspapers? They know. I can't go through with it. It says they're going to arrest the man who did it. And I've been ordered to the field. No, I can't. You wouldn't testify against me. I'd face the firing squad. You couldn't do that. I only carried out your orders. All right. Yes, yes. I'll go through with it. I'll do it. Hello, Operator. This is Special Agent M speaking. The next morning, M and Yvonne were at the airfield. M was dressed in the jumper of a mechanic. He talked to Yvonne in the office of hangar number one. Is everything working out as you planned it, M? Yes. Our suspect trapped himself last night. He works for a spy named Grulla. Grulla has already been arrested. But you haven't proved it. There's no charge against him, Yvonne. He's being questioned about his citizenship papers. Now, wait. I've got to go out on the field. The gasoline truck is coming in now. Now, you stay here and keep out of sight until we're brought back. As soon as we come in, you know what to do. Say, now, he's short of recognition. Yes. Be careful, M. Over here, mechanic. Help this man fill the gasoline tanks. Yes, sir. Colonel, it's tough this morning. We'll fill number one wing tank first. Let's have you hold. Be careful. I got it. All right. Let it come. Ready to fill number two? Just a minute and be ready with number three. All righty. Say, what are you doing? Wait. I've got to change host connection on the tank truck. Did you wave at someone? No. Hurry up. I thought you signaled. How many of those gasoline tanks have you filled? Two, sir. Never mind the third, Sergeant. Take these two men to the hangar office. Lock them in until I come. Yes, sir. We'll take care of it. Take them along, Sergeant. Come on. Are you arresting me? I haven't done anything. Colonel Torres, all men who service this bomber have got to remain on the field until after the test. Here's the office. Get inside. It's a trap. I haven't done anything. I thought you would recognize me, Declan. I took your fingerprints yesterday morning. She's from the police. We're under arrest. I know we are. Yes, Declan. You're under arrest. So is Grulla. He's from the Gasoline of tank number three. You? You are the police, too? That's right. He made me do it. He's to blame. Well, that's confession enough. You made a mistake in trying the same thing a second time, Declan. I knew when you started to change his hose connections, what you were up to. He made me do it. It was Grulla. He's got to pay, too. Don't worry. He will. You'll be tried together. M, how did you know what he did? How did you know there was water in the Gasoline of the third tank of the bomber that crashed? I first suspected water because of the manner in which the motor spluttered and stopped. Then I remembered that the bomber had been in the air exactly four hours. There was enough Gasoline in both tanks one and two to last two hours a piece. That meant the motor stopped when tank number three was turned on. And did he try to put water in the third tank again this morning? Yes, I think so. We'll know the answer in a minute. Well, here's the kind of noun. What'd you find, Colonel? Water. Just as you suspected. If that bomber had taken off, it would have crashed, just as the first one did. Grulla and this man are not only spies. They are murderers. In spite of extreme vigilance, spies often succeed in their vicious work. Sometimes they act themselves. At other times, as in this case, they hire someone to act for them. Grulla was a dangerous spy. The man, Duclaw, only a tool who received money for his acts. Listen for my next story. This is K-7 speaking.
