"Hum, have you any idea who the murderer or murderers were?"

"I know this much: they came up from New York—probably that very evening, and it's more than likely returned the same night."

"Hum, New York parties, eh?"

"Yes; but I think one of them must have been pretty well acquainted in our city, and particularly well acquainted with the murdered woman and her establishment."

"You have no idea who he is?"

"He is called Hen, and has a young lady friend, with whom he is pretty intimate, somewhere on Sixth Avenue, in this city. That's all I know."

Detective Killett became very thoughtful.

At length he asked:

"How did you gain this much information?"

Old Spicer informed him.
