Skeletal remains are found in a cellar below Bath's Georgian tearooms. To Peter Diamond's delight they are not all of medaeival origin, a radius proves to be only twenty years old and bears the marks of a sharp weapon. While a police team painstakingly sift through the cellar looking for the rest of the body, Diamond is distracted by the search for a missing American tourist, the wife of an English Professor who has been behaving very oddly. What Diamond doesn't know is that the professor believes he is on the point of locating the diaries of Mary Shelley written whilst in Bath finishing the manuscript of FRANKENSTEIN. Suspecting the professor of disposing of his wife but unable to prove anything, Diamond concentrates on trying to identify whose remains have been found in the cellar, and by solid old-fashioned detection he does so with shocking result. But before he can begin to work out who might have been the killer, the owner of the city's largest 'antique' emporium is found brutally murdered and the last person known to have seen her alive is the Professor.With consummate skill, wit, erudition and ingenuity, Peter Lovesey has crafted a whodunnit of brilliant complexity and, finally, of total satisfaction.

Peter Diamond, the traditionalist dinosaur of Bath CID, finds the low murder rate in the city a touch frustrating, so he decides to check whether a couple of suicides which his colleague is investigating have been accurately classified. On the outskirts of the city a woman is found unconscious in a hospital car park, but when she recovers she can't remember who she is or how she came to be there. Soon after she is released into the care of the local authority, Diamond has a 'proper' case to get his teeth into when a woman's body is found in the garden of a flat after a somewhat drunken party. None of the other guests knew her and it is not clear whether she slipped, jumped or was pushed, and with no clue as to her identity Diamond has a puzzle to satisfy his quirky talents. In a mystery of stunning complexity, Peter Lovesey amply demonstrates his gifts as the grand master of the contemporary whodunnit.
