"Room 324," he said to himself. "That is on the third floor, I suppose, since they generally start a new hundred for every floor. Wonder if I can get up without being noticed?"

He watched his chance, and slipping past the bell boys, made his way up the stairs, which, on account of the elevators, were but little used. In a few minutes he was in front of the door to Room 324. He tried it cautiously, to find it locked.

"Now if only the keys will work," he muttered, breathing hard, and taking a bunch of keys from his pocket he tried them, one after another.

He had tried four keys without success, when he saw a waiter approaching with a trayful of good things for a late supper in a nearby apartment. At once he moved away down the hallway and did not return until the servant had disappeared from view.

He had five other keys and the third fitted the lock, although rather crudely; so crudely in fact that once the lock bolt was turned the key could not be withdrawn.

"That's bad," he thought. "But as it cannot be helped I'll have to make the best of it. I mustn't stay here too long," and going into the room he closed the door after him.

There was a faint light burning at one of the gas jets and this he turned up, and pulled down the shades of the windows. Then he gazed swiftly around the large room, noting the boys' trunks and traveling bags and several articles of wearing apparel scattered about.

"Oh, if only I can find what I am after," he muttered. "But more than likely they carry their money with them, or else they left it at the hotel office."

All of the trunks and traveling bags were locked, and to force the trunks open seemed at first impossible. One of the traveling bags was slit open with a sharp pocket-knife the bully carried and the contents emptied on one of the beds.

"Not much that I want," muttered Dan Baxter, as he gazed at the collection. Then a jewel case caught his eye and he opened it. "A diamond stud and a diamond scarf pin! Not so bad, after all!" And he transferred the jewelry to his pocket.
