A wealthy businessman is found dead in the locked bedroom suite of his tenth floor Park Avenue apartment, no mark upon his body or visible cause of death. The only other people who had spent the night in the suite were his young wife and her elderly aunt. The wife had both motive and opportunity, but can she be guilty? Enter the famed detective, Fleming Stone, but the only clue he has is the aunt's tale of seeing the dead man's ghost, a ghost she not only saw, but heard, touched and smelled, and who tasted of . . .
