A man returns from the dead, and the body of a mysterious stranger is found in his room…
Hercule Poirot is approached by a woman who claims to have received messages from spirits revealing that Mrs Underhay’s first husband may still be alive. Asked to investigate a missing person case guided only by supernatural warnings, Poirot is sceptical. Yet as he digs deeper, he begins to suspect that the real mystery is not the missing man—but the true motive behind his client’s request.
