This mystery novel has a hero with an unusual twist - at 87 years old he is "the world's oldest detective", living in Warmheart, Florida (surely not a real name for a town?!). He now has no living family, hardly any living friends and his memories and music are all still rooted firmly in the 1930's/1940's. Still, he is a working private eye, taking cases the police don't want and working from his home. Cases such as that of his most recent client, Mrs Weinberger, the elderly and wealthy widow of a famous hat maker, now retired to Florida. Someone in her house has been stealing from her and Harry has a list of suspects - a chauffeur, a butler, a maid, a chef and a gardener, who all have the motive of needing some extra money for various reasons.
The joy in this novel is not with the plot, so much as the humorous and charming character of Harry himself. Most of his information comes from acquaintances as old as he is and, what follows, is an entertaining and enjoyable story, with lots of humour and a well paced plot. I would certainly be interested to read more of Harry's adventures and, hopefully, judging by the end of this novel, there are more to come.
