The creator of the famous criminologist, Dr. Morelle, here gives us four stories of another brilliant detective, whom the newspapers have dubbed "The Amazing Martin Brett." Brett appears to be selfish and lazy, and his effort at solving crimes is entirely motivated by the size of his fee. His attractive secretary (and narrator) is often the butt of his sardonic humor and sexist remarks, which she finds unnecessary and uncalled for. But she puts up with him because she suspects Brett has a secret sorrow, some woman in his past… and, as a detective, he ALWAYS solves his cases!
