the door to let you in? â
For an instant, Bill thought, Wyattâs eyes went blank. But of this he could not be sure. Then Wyattâs eyes widened, his eyebrows went up, his long face was all surprise.
âI donât know why sheâd say that,â Wyatt said. âMust have got things mixed up. It started after I got inside. Where this cat had been.â He snapped his fingers, absently. âHell,â he said, âwhatever it is doesnât come through a closed door.â
He looked intently at Weigand. He said, âWhat are you getting at, captain?â
âBefore you got there,â Bill told him, âthere was someone on the floor above. With Mr. Fitch. With him when he took poison. Probably gave him the poison. Andâthe cat had been up there recently, Mr. Wyatt.â
There was a longish pause.
âSo,â Wyatt said then. âWell, I hadnât, captain. This missusâwhat did you say her name was?â Bill told him. âSheâs got it mixed up.â
âPerhaps.â
âIâd settle for that,â Wyatt told him. âPretty much have to, wonât you? I say one thing. She says another. Doesnât get you anywhere, does it?â
âIt raises a question,â Bill told him.
âAndâIâve answered it. I didnât poison the polo player.â
âAnd you werenât on the second floor?â
âSure I was. I went up with this Mrs. Hemmins andââ
âYou know what I mean. Before that.â
âNo.â
The answer was unhesitating.

Saturday, 11:00 P.M. to Sunday, 12:20 A.M.
They had not let it stop there. For more than an hour after Sam Wyattâs unhesitating denial that he had gone alone to the second floor of Fitchâs duplex, they had taken him over it. But it could not be argued that they had made perceptible progress.
Wyatt had no convenient proof that he could not have been at the apartment some time before he rang the downstairs doorbell and was let in by Mrs. Hemminsâcould not have been in Fitchâs study, and Fitchâs serving pantry, long enough to have concocted, and served, the âeye-openerâ which had permanently closed Bradley Fitchâs eyes; could not, with the poisonâs effect already apparent, have left that floor, gone down in the automatic elevator, got himself readmitted. He said that he had left his apartment and walked the few blocks to the Park Avenue apartment house, that he had gone up immediately and rung immediately, and been let in by Mrs. Hemmins within a few seconds.
But he could not prove this. He had not kept precise track of time. He had not, so far as he knew, been noticed going out and, while this would be checked, checking would hardly help. (It is seldom that anyone says, âOh, there goes Mr. Jones. It is now precisely ten-eighteen and one half.â) He had not, walking that day quiet streets of Manhattanâs upper East Side, encountered anyone he knew. He had not seen the doorman at the Park Avenue apartment house. âProbably off getting someone a cab.â
Wyatt had been entirely reasonable. He had appeared entirely co-operative. Several times, he expressed regret that he could not be more helpful. Once he said, obviously, that had he known about all this in advance, he would have used a stop-watch. âExcept I havenât got one.â
He had been equally reasonable about the cocktail napkin with the neat âNâ in a corner. He had not, at first, recognized the napkin. Prompted, he had agreed that (if the captain said so) it might well be a belonging of Mr. and Mrs. North, and that he might, absentmindedly, have put it in his pocket when he left their apartment the evening before. He had done things like that before. This time, he might very easily have done it. âAll I was thinking of was getting out of there. Three cats.â
He was surprised that the napkin had been found in
