Mystery Mile
Margery Allingham
 When Campion saves him from certain death on the ship over, Judge Lobbett looks into the man's background, and is advised to trust him. So, he takes Campion's advice and brings his handsome son and pretty daughter down to Mystery Mile, a tiny village on a near-island on the Suffolk coast, where Campion's friends Biddy and Giles Paget own a run-down manor house. The night they arrive, a roving fortune-teller visits, and soon afterward the local Rector "St." Swithin Cush, a mild and much-loved man, commits gruesome suicide, leaving a note and some mysterious clues—a red knight from his chess set, and the word "Danger" in encrypted form. Settling in at the manor, the judge calls in an art expert to inspect a possible masterpiece, but as the man (an annoying bore they had encountered on the boat) arrives at the house, the judge vanishes, seemingly inexplicably, while exploring the maze. They search for the judge's secret knowledge, the clue to the identity of crime boss Simister, which has brought such danger, but find only a large box of children's books. Travelling to London to investigate the judge's enemies, and to shake off art expert Barber, Campion and Lobbett's son Marlowe are recalled by a shocking telegram, but find the local Post Office man has exaggerated things—not a body, but Judge Lobbett's clothes, have been found. Next day, Biddy disappears, and Campion soon sees that the shopkeeper is behind it. Thos. T Knapp, a low-class criminal of Campion's acquaintance, arrives with news of their enemies, and they all decamp to London to rescue Biddy, leaving Lobbett's daughter safe in Campion's flat. They break into the house of the fortune-teller, where Biddy is being cruelly interrogated, and after a fight and Campion's use of a smoke-bomb, escape, leaving the gang in disarray. Back at Campion's flat, they see a photo of the judge in a newspaper, and Campion reveals that he had arranged for the disappearance, and hidden the man on a nearby estate, following St. Swithin's advice. They go there, fetch the judge, and he, Giles and Campion decamp for Mystery Mile once more, where they find the household, including Mr Barber, drugged. They retrieve the judge's evidence—a book of stories from the Thousand and One Nights from his set—and Giles and the judge flee using the same path used to smuggle the judge away before, a boat from a beach near some dangerous "soft" - mud that works like quicksand. Campion sits in the hut and deciphers the clue—the art expert's name is Ali Barber. The man comes in, and reveals his secret role as Simister, head of a colossal criminal gang, inherited from his father. He tries to kill Campion with a syringe filled with acid, but Campion breaks through the floor of the hut and falls beneath it. Barber goes to retrieve the book, but is taken by the soft mud, dying horribly. Recuperating later, Campion's friend Stanislaus Oates tells him the secret of Swithin Cush's suicide - he was in fact not a parson at all, having taken the place of his brother who died young. The fortune-teller, a blackmailer working for Simister, knew this and threatened to reveal it. Biddy and Giles Paget plan to marry Marlowe and Isopel Lobbett, respectively, and to sell the valuable painting for a small fortune.
