I grinned at him. “If I was Nero Wolfe, corporal, which I’m not, I would advise you to confine your assurances to the boundaries of your knowledge. That’s his way of putting it. You say positively that nobody took anything. But I notice you stand here in the doorway facing the hall, your back to the room. There’s no glass left in the windows. How do you know a paratrooper didn’t come in that way and take anything he wanted?”
For half a second he looked slightly startled, and for the next half a second the look in his eyes plainly indicated what he would have said, and probably done, if we had been just people instead of a corporal and a major. All he did say was “Yes, sir.”
“Okay,” I told him as man to man. “Probably I counted wrong. Skip it. I always get mixed up when I go above six.”
I went down the corridor to my room, sat on the edge of my desk, and applied logic. Of course it was obvious, if the corporal wasn’t either blind or a liar. Mental operations like figuring the cube root of minus two I leave to Nero Wolfe, but I can do simple addition and subtraction. So I pulled the phone over and got Captain Foster, in charge of personnel, and asked him for the home address of Sergeant Dorothy Bruce.
He was inclined to be flippant, but I told him the request was official and he loosened up. The Bronx or Brooklyn would have been a blow, since I was taking the trip not on information or a hunch, but only on logic, and I was relieved when he gave me a number on West Eleventh Street. That was right on the way home. Toting the receptacle which apparently I had brought along just for the ride, I evacuated via the elevator, went to the car, and started back uptown.
The Eleventh Street number was the only modern structure in a block of old brownstones. Leaving the receptacle in the car, I entered and brushed past the hallman in a military stride, columned left on a guess, spied the elevator, and said brusquely to the girl loitering outside, “Bruce.” Manifestly I was not a man to be questioned. She followed me in and started us up, stopped and opened the door at the seventh, and said musically, “Seven C.” I found it, the second on the right down the hall, pushed the button, and after a little wait the door opened. But it swung only to a gap of a few inches, so as a precaution I unobtrusively planted a foot beyond the line of the sill.
“Oh!” she said in a tone of surprise. I didn’t say pleased surprise. “Major Goodwin!”
