Tragically one of the guests was found murdered next to the newly installed telephone. There seemed no motive for the murder. As Holmes investigated, old scandals, old enmities, old hatreds began to surface. Had Holmes missed something? Was it perhaps a case of mistaken identity? And who had the murdered man been trying to call on the telephone?
This tale of pure detection, by John Hall, the author of the best selling novel The Travels of Sherlock Holmes, is a classic of the genre.
