This collection of 25 Hercule Poirot adventures is compiled from short stories written by Agatha Christie for The Sketch magazine in 1923 from March to December. In these stories, including "The Disappearance of Mr. Davenheim", "The Veiled Lady", and "The Adventure of the Egyptian Tomb", the eccentric private detective slowly and surely solves mysteries involving jealousy, revenge, and greed. These stories were well-received at the time and cemented Christie's reputation as the worthy successor to Arthur Conan Doyle.

In Agatha Christie’s short story, “The Case of the Missing Will,” Poirot must help clever student Violet Marsh meet the terms of an unusual will by her Uncle Andrew. She must live in his house for a month and “prove her wits” if she is ever to receive his fortune. But is there another will? This short story originally appeared in the October 31, 1923 issue of The Sketch magazine.

Inspector Rudge does not encounter many cases of murder in the sleepy seaside town of Whynmouth. But when an old sailor lands a rowing boat containing a fresh corpse with a stab wound to the chest, the Inspector's investigation immediately comes up against several obstacles. The vicar, whose boat the body was found in, is clearly withholding information, and the victim's niece has disappeared. There is clearly more to this case than meets the eye - even the identity of the victim is called into doubt.

The derelict house on the edge of the sleepy seaside town was a haven for courting couples, down-and-outs - and someone with altogether more sinister intentions. It was there that they found the corpse of 17-year-old Jenny Hyde. She'd been strangled.
