The bones of seven girls, carefully cleaned and carefully preserved, were found many years ago... This is all that Sergeant Ryan DeMarco knows about the unsolved case that he will have to take on, albeit against his own will. But if there's one thing Ryan is sure of, it's that a killer always leaves a trail. All they need is a person who can understand them. DeMarco has no idea that he will have to battle not only a mysterious criminal, but also demons from his own past - the burden of guilt for the death of his own son and lost marriage, difficult memories from childhood and the inability to open his feelings even to the closest people. Will Ryan be able to overcome all the difficulties and not only solve the case, but also save his new relationship? This story is about things that were buried deep in the past: memories, regrets, secrets... and crimes.
