"Then we must have a sharp eye on the passengers arriving by that train."
"But it is usually quite a long train, I believe; and there are so many ways of getting out of the Grand Central Depot—can we two manage the thing alone?"
"I was just thinking of that, and I fancy we had better have a little help. Do you remember Stark?"
"What—your old friend, Silas?"
"The same."
"Yes, I remember him well."
"Glad to hear it. You've no objection to my calling him in?"
"None in the world. I shall be glad to have his assistance."
"Then I'll send for him and Rouse. It so happens they are in this neighborhood. Excuse me a moment, and I'll telephone for them," and Detective Killett left the room.
In a few moments he returned, and ten minutes later Silas Stark and Reuben Rouse entered the apartment.
