“I’m not thinking about murder now, I’m thinking about that will. Where was it drawn? In the office of Dunwoodie, Prescott & Davis. Where was it kept? In a vault in that office. Who benefited by it? Chiefly Miss Karn. Did she know that? Yes; Mr. Prescott let her read it shortly after it was drawn, having been instructed to do so by Mr. Hawthorne. Did you know that? I don’t know. Did you?”

“No,” said Davis curtly. “It was none of my business. Prescott drew it.”

“But you have access to the vault?”

“I’m a lawyer, not a snoop, Mr. Wolfe.”

“But isn’t it plausible that Miss Karn told you about it? Couldn’t you have learned it that way?”

“It may be plausible, but she didn’t. I knew nothing, absolutely nothing, about the terms of that will until Miss Karn told me last night. Has Prescott told you I did?”

“Oh, no. No one has told me anything, really. They’re all like you. I’ve sat in this confounded room over seven hours, and I know very little more than when I entered it. I don’t resent it that each of you people has something to conceal — everybody in the world has — but it has never taken me so long to find a loose end. Let’s start somewhere else. You say you are Miss Karn’s friend and lawyer and she consults you. Did you advise her to come here this afternoon to negotiate with Mrs. Hawthorne?”

“No. Why?”

“Because she came.”

“She came here?”
