This is the fourth book in the Davenport series. It's April and the start of the tennis season at Greenway Tennis Club on the South side of Glasgow. Some of the juniors have just finished their first coaching session. Two girls go to one of the changing rooms and discover the body of an intermediate girl. DCI Davenport and his team are called in to investigate but before the denouement in the upstairs room of the tennis club, there are to be two more deaths.
