Blood is thicker than water... and runs just as freely...When the body of a man is discovered face down one morning in the swimming pool of his upmarket family home, the team wonder if it is the result of a tragic accident or serious foul play.DI Tom Janssen is currently suspended pending the outcome of the events at the close of his previous case. Using the time away from the office to consider his future, and how this will impact on his family life, Tom is invited to attend a school reunion which he reluctantly agrees to. Coming face to face with people he hasn't seen in years leads to more than a reunion of old friendships. Some people find it hard to let go of the past while others foster long-held grudges. It isn't long before Tom finds old feuds rekindled and scores that aim to be settled... one way or another.Finding himself at the centre of a murder inquiry - only this time as a witness rather than an investigator - can he steer clear of the case or will temptation, and a search for the truth, be too much for him to ignore.
