“There’s nothing more for me to do here, Muller,” said the physician, as he bowed to the commissioner and left the place. Muller examined the pockets of the dead man. “It’s probably a case of robbery, too,” remarked the commissioner. “A man as well-dressed as this one is would be likely to have a watch.” “And a purse,” added the detective. “But this man has neither—or at least he has them no longer.” In the various pockets of the dead man’s clothes Muller found the following articles: a handkerchief, several tramway tickets, a penknife, a tiny mirror, and comb, and a little book, a cheap novel. He wrapped them all in the handkerchief and put them in his own pocket. The dead man’s coat had fallen back from his body during the examination, and as Muller turned the stiffened limbs a little he saw the opening of another pocket high up over the right hip of the trousers. The detective passed his hand over the pocket and heard something rattle. Then he put his hand in the pocket and drew out a thin narrow envelope which he handed to the commissioner. Holzer looked at it carefully. It was made of very thin expensive paper and bore no address. But it was sealed, although not very carefully, for the gummed edges were open in spots. It must have been hastily closed and was slightly crushed as if it had been carried in a clenched hand. The commissioner cut open the envelope with his penknife. He gave an exclamation of surprise as he showed Muller the contents. In the envelope there were three hundred-gulden notes. The commissioner looked at Muller without a word, but the detective understood and shook his head. “No,” he said calmly, “it may be a case of robbery just the same. This pocket was not very easy to find, and the money in it was safer than the dead man’s watch and purse would be. That is, if he had a watch and purse—and he very probably had a watch,” he added more quickly. For Muller had made a little discovery. On the lower hem of the left side of the dead man’s waistcoat he saw a little lump, and feeling of it he discovered that it was a watch key which had slipped down out of the torn pocket between the lining and the material of the vest. A sure proof that the dead man had had a watch, which in all probability had been taken
