Welcome to the fourth volume of locked-room mysteries. Following the original twelve stories in the Professor George Wellbelove Investigates series, a final six new and never-before-told mysteries are presented for your delectation. Tales that are puzzles as much as captivating stories. We have the classical murders made to look like suicide, murders that simply defy logic, crimes that in the normal world, one just wouldn't believe could happen and even $2M of jewellery that vanish into thin air. As a wonderful and memorable backdrop, the series of stories is set in the majestic, spired city of Cambridge, England. In the course of their duties, the long-suffering Chief Inspector Peter Meadows and his assistant, Sergeant Roger Carter attend the scenes of the crime and make their reports. To the Chief Inspector's eye, many appear simple open-and-shut cases which he is happy to close without further investigation. That is, until his friend and colleague, Professor George Wellbelove, university lecturer in Forensic Science, gets involved. The Professor's great ability to think outside the box, bestows on him the gift to spot small, innocuous clues that lesser mortals miss - including the Chief Inspector. Each story has its own personality and some pay homage to the great crime writers such as Agatha Christie, Edgar Allan Poe, John Dickson Carr and more modern writers like Stephen Leather in their writing style and plot development. Eighteen fresh stories, most unique, in this much-loved sub-genre of detective fiction, to seriously challenge the reader's little grey cells. So continue the journey into the world of locked-room mysteries - where the unlikely and improbable are, in fact, just reality.
