When the body of a young woman is found on a Dutch island, veteran detective Inspector Jaap Rykel of Amsterdam's Murder Squad is summoned; although a suspect immediately confesses, the man has no motive and no connection to the victim. In this third book in a quartet of novels by British author Jake Woodhouse, Rykel soon hears of a similar murder and confession on the other side of Holland, and the detective finds himself on the trail of a serial killer for the first time. With his every lead amounting to nothing, Rykel must determine whether the killings are random or whether they have an underlying logic that might make the next murder preventable. London's Daily Mail praised this 2017 novel for "a strong sense of place matched by storytelling that keeps the plot accelerating."
