Abel Marks was not a nice man, and when he's found murdered in his Razor Street flat, suspicion falls on Carol Marks, the young women he'd married just a few hours before. It was she who'd found the body, and she who'd agreed to marry him to pay back the money that her father owed the ruthless merchant.
But Inspector Combridge soon discovers that both William Merritt, the girl's father, and Miss Barman, her aunt, had called upon the dead man just before his death. Each had had a motive for murder. When the trial begins, both women confess to the crime, but one or more of them is lying. Because there was a fourth visitor to Razor Street that afternoon!
One of Fowler Wright's finest courtroom puzzles.
