Whilst a guest of Lord and Lady Blatchington, Dick Prescot finds a stranger dead in the library, a revolver tied to his hand with a piece of string. It transpires that the victim had a profound interest in gaining possession of the world-famous Blatchington rubies, and that very night an attempt was made to steal the gems. Armed with these clues, Prescot attempts to solve the mystery. Many of those attending the country house party were behaving in a suspicious manner, but Prescot finds his sympathies engaged with the very persons he had most reason to suspect. The imminent arrest of the most popular member of the party leads to the summoning of the great detective Mr Henry Wilson, formerly superintendent at Scotland Yard… ABOUT THE AUTHORS G.D.H. and Margaret Cole were a husband and wife detective fiction writing duo who wrote over thirty novels between 1923 and the early 1940s. Much admired at the time (‘The collaborating Coles, have long been known as writers of skilfully constructed detective tales’ New York Times ; ‘Among the most remarkable and efficient of English detective story writers’ Times Literary Supplement ), their success is all the more remarkable because they both led sterling careers in addition to their prodigious crime-writing output; George as an Oxford University economist and Margaret as a socialist politician. Their best-known character, Superintendent Wilson, starred in twenty-three novels. Originally a conscientious Scotland Yarder, Wilson is eventually forcibly retired into private practice after catching-out an ex-Home Secretary. Among their other literary creations are medic turned private detective, Dr Ben Tancred, the prickly and difficult Inspector Tom Fairford and the gentle, old-lady sleuth, Mrs Warrender. G.D.H. Cole died in 1959 and Margaret in 1980.
