From the private files of Scotland Yard's in house museum come 19th and 20th century talkes of murder which mark some of the most infamous cases ever investigated by one of the world's premier investigative forces. Included are the first use of finger print technology; the first time `The Yard' used the Press to help hunt down a killer; the first use of the now well-known `wanted poster'; the early use of photography; the call box and the teaming up of Inspector and Sergeant as an investigative team. Method of murder are also explored as detectives uncover murders by poison, a Victorian favorite, dismemberment, axe, acid, rope, gas, gunshot and knife. All areas of British society are included from the lowest dressmaker, the poor farmer, the travelling salesman and the truck driver to the gentleman gambler, the well paid attorney and even a police officer. And even though the detectives of Scotland Yard rarely miss their man, or woman for that matter, cases which have yet to be stamped-case closed-are also part of the history and files of this most interesting collection of tales from the exhibits and files deeply held within the walls of the Black Museum.
