Return of the Dead

When a person has stood at the gate of hell, the world can no longer restrain him with common sense. Ryan Crowley died twice. The first time was when he was seven years old, he fell into the collapsed layer of the family tomb and was trapped in absolute darkness and silence for three days. The second time was five years ago, an "accident" that has not yet been made public. Now he's back. Because some debts cannot be repaid by living people. For some trials, only the dead are eligible to execute them. "If death is a long sleep from which one cannot wake up, then those who return from the other side are destined to become night watchmen for those who have not slept."
