"What do I know?"
"You dashed well know that Craver was the man who sloped on the postman's bike on that night. You tried to rope him into the business, hut failed."
"For the time being I have failed, Mr. Lemby; but I may rope him in, as you put it, later. Well, and what else do I know?"
"You know that Mrs. Vence is a liar."
"Oh, do I?" Lady Wyke raised her eyebrows.
"Yes. Claudia saw Mrs. Vence the other day--yesterday, in fact, and she said----"
"Mrs. Vence or Claudia? Do be accurate."
"The old woman," growled Lemby, who did not like to be interrupted. "She said as how I came down the stairs with my knife and murdered Wyke."
"Well, the knife with which the crime was committed is yours, you know."
"Who says so? How do you know?"
