Six students went into the Standedge Tunnel, the longest canal tunnel in England, on a private boat. Two and a half hours later, the boat reappeared carrying only one of the students, Matthew. He had been knocked unconscious and has no memory of what took place. The police suspect he killed his friends, hid the bodies and later moved them to an undisclosed location. When a jailed Matthew contacts a famous author asking him for help in return for information he claims to possess about the author’s long-lost wife, it’s an offer that can’t be refused. But before the author can prove Matthew’s innocence, he must first answer a far more unusual question: How did five bodies disappear into thin air?
