Carole and Jude are next door neighbors and amateur sleuths who live in Fethering, a town in England. In this 14th volume in the series Jude has fallen for Piers, a suave, handsome businessman obsessed with "real tennis", a game played on an indoor court. Piers takes Jude to watch a real tennis match at Lockleigh House Tennis Club where she meets his friends and fellow enthusiasts.
Afterwards Piers convinces Jude to take lessons in the sport as well. Jude's preoccupation with Piers leaves Carole feeling neglected so Carole decides to look into an old unsolved mystery, 'the girl in the lake', by herself. Meanwhile, the body of an elderly tennis club member, Reggie Playfair, is found dead on the Lockleigh House tennis court. Though Reggie's death is apparently from natural causes Jude is suspicious. Thus Carole and Jude undertake simultaneous - but largely independent - investigations.
During their sleuthing Carole meets a woman looking for her long lost daughter and Jude discovers that the Lockleigh House Tennis Club is a late-night trysting place for lovers. The book has some fun, interesting characters and the dual investigations dovetail nicely at the end.
I do have a quibble with Reggie's cause of death but - since the book is a cozy - I'll give it a pass. I'd recommend the book as an entertaining light mystery.
