An unusual puzzler from the years shortly after WWII. An amateur orchestra is planning a concert. They need a professional violinist and a professional clarinetist. The first is the famous Lucy Carless, the second presents difficulties. The polish refugee originally scheduled to play the clarinet walks off in a huff after exchanging words with Lucy, and a last-minute replacement must be found. When Lucy is found murdered backstage, the police investigation focuses both on the local members of the orchestra and their internal bickering, as on the strange tale told by the replacement clarinetist. Who sent the wrong car at the wrong time to pick him up at the station, thereby ensuring that he would be too late for the concert? Where was Mr. Ventry, the womanizing organist, in the hours leading up to the concert? Why did Lucy dislike the work of Dickens so much?
Francis Pettigrew, reluctant amateur detective, is drawn into the investigation thanks to his role as treasurer of the amateur orchestra. While the energetic and conceited Inspector Trimble vigorously pursues alibis and eyewitness accounts, Pettigrew and the Chief Constable drink whisky and discuss the matter at leisure, in the best tradition of the armchair detective. A good knowledge of music might help the reader in figuring out the complex cascade of events triggered by the culprit, but even without that knowledge, I found it an enjoyable mystery. One of the things that I liked was that the mystery unfolds step by step, with more and more discordant elements being uncovered that seem to hint now at this, now at that. I was not wholly surprised by the identity of the murderer, but I would have had to agree with Pettigrew's original assessment that the person he believed had done it, couldn't have done it !
