A small old man in pyjamas is found dead at the bottom of the stairs. His wheelchair is next to him—was he pushed or did he fall? His part-time carer Nancy, a pretty young woman, is suspected of his murder, but she is missing without trace. Detective Inspector Angel is drawn into an intricate web of family lies and deceit. The dead man's daughter is hiding something, and his granddaughter seems incapable of telling anyone the truth. The pressure is on for Angel to unravel the mystery and identify the killer before another body is found.
