"Has von Felsen turned up?" I asked him.
He shook his head and grinned. "I think we could trace him. I have a clue, but it may not be desirable to follow it up."
"Which means?"
"I expect you know more than they have told me; but I know enough to make me doubt whether his father is very anxious to see him again. Of course if you take steps against these men, it may have to come out, the whole of it."
"What's the clue?"
"That Jew girl, Hagar Ziegler, left the city this morning for Hamburg, with a companion. There's a boat sails to-day for Philadelphia."
"And the sex of the companion?"
He shrugged his shoulders and smiled significantly. A woman--apparently. "But only one berth has been booked for a woman, by wire of course; although, by a coincidence, a steerage passage has been reserved for a male passenger."
"And what does Herr Borsen propose to do?"
"Nothing. And you?"
