Hugenay chuckled. “I like spirit in a boy,” he said. “However, it should stop short of utter rashness. I am not alone and — But why make threats? I have something to offer you for your co-operation. Help me, and I’ll help you.”

“Help me how?”

“The boy Harry whom you met at Bert Clock’s house. His father is in prison. I will enable you to prove he is innocent. I will take the paintings — you will get an innocent man out of jail. Surely you won’t refuse to do that?”

Jupiter thought furiously. Then he nodded. “All right, I’ll help if you’ll do that. But there’s one thing more you’ll have to do.”

“And what is that, my plump but clever young friend?”

Jupiter told him exactly what had happened to Bob and what the situation was — that he was supposed to be picked up by a van in less than half an hour to take him to the place where Mr. Jeeters and the others had Bob and Harry.

Hugenay uttered a few expressive words in French.

“Those idiots!” he said. “I did not think they would act so swiftly. I planned to get the pictures and be gone before they could do anything!”

“You knew about them?” Jupiter asked, puzzled.

“Certainly I knew about them. I know far more than you think. I have been in the city for two weeks, casting about for a clue. I have — certain methods. If you wish, you may assume that I have had the telephone wires of these individuals tapped and listened to all their secret conversations — however, I will not say yes or no to that. Obviously, though, there has been a change in plans today. We must foil those plans.

“Yes, boy, I will help you rescue your friends, then we will find those paintings, and by this time tomorrow I will be five thousand miles away. You must start by following instructions. At the proper time you must be waiting outside for the van. Get in and go with the driver. I and my men will follow behind, discreetly. Leave the rest to me. The less you know, the better — ”

Realizing that he had to trust Hugenay, Jupiter eased out through Green Gate One and went back to his home. He was beginning to be a little sorry he’d ever thought of investigating a screaming clock, but it was too late to change things. Anyway, he knew that Hugenay was very clever and resourceful, and he felt sure that the Frenchman could outwit Mr. Jeeters and Jerry and Carlos.

Jupiter entered the house, where his aunt and uncle were watching television. He told them Bob had phoned and wanted to see him. They readily gave him permission to spend the night with Bob, and Jupe went up to his room. He put on a warm jacket and thrust the messages into the inside pocket.

Downstairs, he said good night to his aunt and uncle and then walked out to stand in front of the main gates of the salvage yard.

Hugenay was waiting there for him. He came over and put his hand on Jupiter’s shoulder and spoke earnestly.

“Don’t forget we’re working together now,” he said. “First we have to get Bob and Harry free. When the van comes, get in and don’t give any sign you know I am following you. If in any way they get suspicious. I leave it to your cleverness to know what to say. Now I am leaving you.”

He faded away into the darkness. If he had a car waiting, Jupiter could not see it. Possibly it was hidden at the other end of the salvage yard. Jupiter waited. It was very quiet and dark here beyond the outskirts of town, and he shivered a little.

Headlights cut the darkness. A small van came slowly down the street. For a moment the headlights shone clearly on him. The van stopped. The door opened and the little man, Jerry, leaned out. “All right, kid, hop in!” he rasped. “And for your own sake, and your pals’, you’d better not be trying any tricks!”

The van moved steadily along in the direction of Hollywood. Carlos was driving, and Jupiter was squeezed in between him and Jerry.

“You have those messages with you, boy?” Carlos demanded.

“Yes, sir, I have them,” Jupiter said, sounding unusually meek and humble.

“That’s good,” Jerry muttered. “Because if—what is it, Carlos?” Carlos was staring into the rear-view mirror. “I think we’re being followed. There’s been a car behind us for the last couple of miles!”

“Followed!” Jerry exclaimed. He grabbed Jupiter, hard. “Kid, if you called the cops — ”

“No, sir, I didn’t!” Jupiter sounded frightened, and only part of it was acting. They had spotted Hugenay’s car, and the whole plan with Hugenay was in danger of failing.

“Then if it isn’t the police, who is it?” Carlos demanded. “Quick, answer me! Don’t stall or I’ll know you’re lying!”

“If we’re being followed,” Jupiter said rapidly, “it might be somebody else who wants the messages, too. Somebody stole the screaming clock yesterday. If it wasn’t you, that shows somebody else is interested, and that same person might have been watching my house and seen you pick me up. Naturally he’d want to know where I was I going.”

“That’s it!” Jerry exclaimed. “That clock — Harry told Jeeters all about it. I’ll bet the kid’s right. Someone else is trying to find the loot. Carlos, you’ve got to shake them.”

“Leave it to me,” Carlos said grimly. “There’s a freeway only a mile ahead and I’ll get on to it. Then let them try to follow!”

He maintained the same speed for another couple of minutes. Then, as they approached the freeway, he put on speed, dashed up an entry ramp, and a moment later was in the midst of a stream of fast-moving traffic heading towards Hollywood.

The freeways of Los Angeles and Hollywood are a great network of concrete highways which connect the city of Los Angeles and the surrounding territory. A tremendous number of cars stream along them all day and most of the night. Now they were on a six-lane highway, and all six lanes contained cars and trucks moving at great speed, Carlos stepped on the accelerator and began to cut in and out of the traffic. In a minute or two anyone following would be hopelessly lost among the cars and huge trucks Carlos, however, was not satisfied until he had been threading in and out of the dense traffic for ten minutes. Then he cut to the outer lane and swung sharply down an exit ramp.

He slowed as he hit the city street below them and watched the rear-view mirror intently. Apparently he was satisfied, for after a few moments he relaxed.

“Nobody followed us out of that exit,” he said. “If anyone was tailing us, we’ve lost them.”

As Carlos proceeded at a normal speed, Jupiter’s spirits sank steadily lower. He had been counting on Hugenay. Now Hugenay had lost them, and could be of no help.

The van turned into a driveway between two old houses. In the rear was a large, two-car garage. Carlos beeped the horn once, and one of the sliding doors went up. The van eased inside and the door went down again.

Carlos and Jerry climbed out, hustling Jupiter along. Jupiter saw Mr. Jeeters waiting for them, and behind him Bob and Harry, tied to chairs.

“Any trouble?” Mr. Jeeters asked. “You’re a little late.”

“Someone followed us,” Carlos reported. “We had to take time to throw them off the trail. The kid swears it wasn’t cops. May have been whoever stole the screaming clock yesterday Anyway, whoever it was, we lost them.”

“Good.” Mr. Jeeters fixed hard eyes on Jupiter. “I’m sure our young friend here is too smart to have been trying any tricks. All right, boy, now the messages. Let’s have them.”

Jupiter fumbled in his pocket. He brought out a piece of paper.

“Here’s the first message, Mr. Jeeters.”

Jeeters took it and read it. “I suggest you see the book. Yes, your friend already told us that one. What book does it mean?”

“I don’t know.”

“Well, doesn’t the second message tell us?”

“Here it is, sir. You can see what it says.”.
