Hercule Poirot lives to solve mysteries, and the three episodes included in this boxed set provide him with perplexing cases at home and abroad. "The Third Floor Flat" begins with Poirot suffering from a terrible cold brought on, he believes, by a lack of cases and the subsequent decay of his "little gray cells." A trip to the theater fails to cheer the sleuth, but when Poirot returns home he finds a murder mystery unfolding on his own doorstep. "Triangle on Rhodes" finds Hercule enjoying the final days of a vacation on the Greek island. When a woman is poisoned in his hotel, only Poirot can untangle the threads of passion and betrayal that will eventually lead him to the murderer. In "Problem at Sea" Poirot and Hastings take a Mediterranean cruise to Egypt, but their trip turns out to be anything but relaxing when a murder takes place. The passenger list is filled with fascinating suspects, and Poirot sets to work to solve the crime.
