Wolfe cocked an eye at me. “I meant no offense. My intentions—”

“Forget it. You’re under a strain. Mr. Hackett’s life is in jeopardy and it makes you nervous.”

We got to details. Jane Geer was making a nuisance of herself. I understood now, of course, why Wolfe had refused to see her Wednesday evening. After sending me to get her he had conceived the strategy of hiring a double, and he didn’t want her to get a look at the real Nero Wolfe because if she did she would be less likely to be deceived by the counterfeit and go to work on him. That meant she was seriously on his list, but I didn’t take the trouble to inform him that in my opinion he could cross her off, since he would only have grunted. She had phoned several times, insisting on seeing him, and had come to the house Friday morning and argued for five minutes with Fritz through the three-inch crack which the chain bolt permitted the door to open to. Now Wolfe had an idea for one of his elaborate charades. I was to phone her to come to see Wolfe at six o’clock that afternoon. When she came I was to take her in to Hackett. Wolfe would coach Hackett for the interview.

I looked skeptical. Wolfe said, “It will give her a chance to kill Mr. Hackett.”

I snorted. “With me right there to tell her when to cease firing.”

“I admit it is unlikely. Also, it will convince her that Mr. Hackett is me.”

“Which still will not shorten his life or lengthen yours.”

“Possibly not. Also, it will give me an opportunity to see her and hear her. I shall be at the hole.”

So that was really the idea. He would be in the passage, a sort of an alcove, at the kitchen end of the downstairs hall, looking through into the office by means of the square hole in the wall. The hole was camouflaged on the office side by a picture that was transparent one way. He loved to have an excuse to use it, and it actually had been a help now and then.

“That’s different,” I told him. “If you see her and hear her you’ll know she has a heart of platinum.”
