Hercule Poirot, Agatha Christie's brilliant detective, returns to find his would-be employer murdered, too many suspects, and the detective directing the local police investigation ignoring his polished investigative technique. The two butt heads compete to solve the case until a second body is discovered, murdered in the same manner as the first.
Poirot's razor-sharp perception and in-depth knowledge of criminal history are required to connect both murders as he successfully works toward an unanticipated conclusion.
