The Rayner-Slade Amalgamation by J.S. Fletcher

It was to a hastily called together gathering of high police officials that the three visitors told all they knew. One after another they related their various stories -- Chettle of his doings and discoveries at Hull, Allerdyke of what had gone on at the hotel, Appleyard of the mysterious double identity of the woman who was Miss Slade in one place and Mrs. Marlow in another. The officials listened quietly and absorbedly, rarely interrupting the narrators except to ask a searching question. And in the end they talked together apart, after which all went away except the man who had kept his hands on the reins from the beginning. He turned to his visitors with an air of decision.

"Well, of course, there's but one thing to be done, now," he said. "We must get a warrant for this woman's arrest at once. We must also get a search warrant and examine her belongings at that private hotel you've told us of, Mr. Appleyard. All that shall be done immediately. But first I want you to tell me one or two things. What are those two men you spoke of doing -- the Gaffneys?"
