Cast & Crew
Tom Gannell, a criminal lawyer, detects an intrigue between his wife, Emma, and a college student, Sorley, who tends furnaces on their block. When Sorley goes to the cellar, his wife goes to the piano and plays "The End of a Perfect Day," and maddened by his wife's faithlessness, Gannell follows Sorley and kills him. The following day, the Kirkwoods leave on their annual trip to Florida; a coat belonging to Kirkwood and a pack of his cigarettes are found near the body; hearing of the murder, he returns home and is arrested for the crime. Kirkwood is defended by Gannell and found guilty. Mrs. Kirkwood, who suspects Gannell, induces the police to tap a telephone conversation between herself and Gannell: while talking she has her maid play "The End of a Perfect Day" on the piano. Finding his living room empty and hearing the sound of the furnace being raked, Gannell breaks and confesses his guilt but defies her to prove it.
