regretfully at the envelope.
Clearly, Retto had not been far from Mr. Potter at the time of the
accident. Perhaps the missing millionaire was hiding downtown in New
York.

"I must make some inquiries in that neighborhood," thought Larry, as
he arose to go.

"Another thing," Grace said. "That man Sullivan was in front of the
house again this morning."

"I must see him!" exclaimed Larry. "I'll make him tell what his
object is. This thing has got to end!"

He was fiercely determined that he would force some information
from the politician. Evidently Sullivan had a game on hand which the
reporter had not yet succeeded in fathoming. "I'll hunt him up at
once!" he added, as he bade Grace good-bye.

"Be careful," she cautioned. "He is a dangerous man."

"I will," Larry promised.

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

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
