At a loose end, gentleman-swindler Mr Collin is drawn into spending an evening in Hamburg's underworld by a Russian Grand Duke in disguise - but his new friend delights in sailing close to the wind. From the elegant night club Papillon de Nuit to an illegal gambling den, can Mr Collin keep their necks and their pocketbooks intact? Frank Heller was the first internationally famous Swedish crime writer. The son of a clergyman, to avoid arrest after a financial fraud he left Sweden for the continent. In desperate straits after losing the swindled money in a casino in Monte Carlo, he tried his hand at writing novels with immediate success, and produced forty-three novels, short stories and travelogues before his death in 1947. This is the third Mr Collin short story available from Kabaty Press, with the first two being "The Absent-Minded Gentleman" and "The Mystery of the Lost Bullion"
