Pearls Before Swine — Margery Allingham

A tall, thin man with overly large spectacles, he is deceptively unobtrusive when tracking down a killer and uncannily capable of predicting the deadly twists of a criminal's mind. He is unquestionably a gentleman, but even Lugg, his dauntless valet, and his friends at Scotland Yard don't know all the secrets in Campion's past--or the confidential cases he has covertly solved while in His Majesty's Service.

A BODY NOBODY WANTED
It was most unfortunate that Edna, Dowager Marchioness of Carados, found a strange woman in her son's bed the night before his wedding. It was even more unfortunate that the woman was obviously dead. Under the circumstances, Campion couldn't blame Edna for moving the body. He just wasn't pleased that she brought it to him. Campion wanted to believe that his friend Johnny, the Marquess of Cara-dos, wasn't the woman's killer, but the clues in the case were baffling: a string of fake pearls, two bottles of rare wine, a bride who brought home a boyfriend ...and a pet pig.
