But he could not find Sullivan. For once that wily politician denied himself to reporters, and kept out of their way. He was sought by a number of newspaper men, for the matter of a candidate for the eighth assembly district was again to the fore, and the henchmen of Kilburn and Reilly were making rival claims as to Sullivan's support.

"Where is Sullivan?" was the cry that went up, and in the next two days that became almost as much of a mystery as the disappearance of Mr. Potter.

"Get busy, Larry," advised Mr. Emberg, and Larry did his best to follow the advice.

Three weeks passed, and Sullivan was not found. His family professed not to know where he was, and the best newspaper men in New York could not find him. Larry was working on the case with all the energy he had thrown into the Potter disappearance.

Meanwhile the young reporter kept a close watch on the hospital where Retto was. The operation had been a success, but the patient was

in a fever, during which he was out of his mind. He could not recognize anyone, much less talk intelligibly. Larry made several calls at the institution, but it was of no use.

"You can't see him," said the nurse, when he had paid his usual visit one day, "but he is much better. I think by the day after to-morrow you can talk to him. His fever is going down and he has spells when he talks rationally. There was another man in to see him to-day."

"I thought you said no one could visit him."

"Well, we made an exception in this case. The man was a private detective, searching for a missing man, and he wanted to see all the patients. He looked at your friend last, and went off, seemingly quite excited."

"What missing man was he looking for?" asked Larry.
