This is an automatically translated description

Former policeman John Rebus can't enjoy his retirement as he should when the skeleton of a private detective who went missing more than a decade ago is discovered on the outskirts of Edinburgh. Rebus was once involved in this disappearance, but he never solved the case, and now it has turned into a murder case. Rebus remembers his investigation well: when it stalled, the parents of the missing boy began to complain that the police were covering up for their own. Now, Rebus's friend Siobhan Clarke has joined the investigation, but she can't imagine how many long-buried secrets will come to light. And that her former teacher also has secrets that he would prefer to leave in the past... The new novel by the famous Scottish writer Ian Rankin proves once again that the unsurpassed Rebus is always on top of his game.
