He had put it in the refrigerator at Bert's apartment on the night of his death, but no one can remember seeing it since then. Archie fails to learn its whereabouts, but Wolfe surprises him by asking him to bring Buhl, Arrow, the Tuttles, and the Fyfes to the office. Wolfe informs the group that he has decided to notify the police about Bert's death and explains his theory of the crime. The ice cream Paul bought had been packed in dry ice to keep it cold; the murderer emptied the hot-water bags and placed the dry ice on top of them to lower Bert's body temperature to dangerous levels without causing frostbite burns or leaving any traces once it evaporated. Wolfe has learned that Tuttle provided an alibi for Bert during the murder trial, and that Bert had returned to New York to check into it. He had visited the landlady from whom he and Tuttle had rented rooms 20 years earlier, and Saul confirms that Tuttle has recently visited her as well. Based on David's statement that his father had refused Louise permission to marry Tuttle, Wolfe accuses Tuttle of opening the window to cause the elder Fyfe's death in revenge, then of causing Bert's death to prevent him from uncovering the truth. Tuttle is convicted of the murder of the Fyfes' father, and Arrow sends Wolfe and Archie a large payment in gratitude for clearing his name. In a 1957 installment of "The Criminal Record", "Saturday Review" magazine's weekly column about detective literature, "A Window for Death" and the other two stories collected in "Three for the Chair" were pronounced the "usual smooth sailing … Trio of Nero Wolfe yarns finds big boy still lining 'em up and mowing 'em down." Anthony Boucher called the book "one of the best of Stout's threesomes ... The situations and solutions are unusually good ones, and the stories are rich in unexpected Wolfiana." Some 30 years later, "A Window for Death" was quoted in a "New York Times" feature about the significance of gastronomy in mystery stories. In addition to quoting a passage that describes how Fritz prepares one of Wolfe's favorite warm-weather meals, Brazilian Lobster Salad, the newspaper reprinted the recipe.
