The Rising Tide by Ann Cleeves
Fiction

What’s it about: For fifty years a group of friends has met for reunions on the island where they all originally met during a school retreat. This time, one of them ends up hanged and DI Vera Stanhope and her team must find out what led up to the murder. Are secrets from the past to blame or are the motives for the murder of a more recent variety?

Reviewers say: "Cleeves crafts a clever central puzzle, then confers remarkable emotional complexity using her keenly drawn characters' advancing age, wistful nostalgia, and thorny shared history. A pinwheeling third-person narrative drives the pace, while Vera's candor tempers the plot's darker elements. Fair-play mystery fans will delight.” (Publishers Weekly).

Good to know:  The great Brenda Blethyn portrays the cantankerous but brilliant detective in a series of TV movies, available on dvd.
