In this dramatic and perceptive account of the men who operate the finely geared machine that is Scotland Yard's famed Murder Squad, the author has written a story more gripping than a dozen hand-tailored thrillers. Here is the real key to what makes a great Yard detective, demonstrated in action both in Britain and thousands of miles away. For the Murder Squad is in being to help any police force of the Commonwealth that urgently, requires its assistance in a murder hunt. In these pages the reader can watch the operating of such renowned Murder Squad teams as Detective Superintendent 'Bill' Baker and Detective Sergeant John O'Connell, hunting a killer who had terrorized Bermuda, and Detective Superintendent John Capstick and Detective Sergeant William Hed-don, out tramping the Welsh countryside to find, first, a vanished victim, and then a very self-possessed murderer. Or he can follow the progress of 'Four-Day Johnny' du Rose, seeking the killer of a Polish countess, and observe how Detective Superintendent Maurice Osborn trapped a little girl's brutal murderer.
