The neat-freak Belgian Hercule Poirot returns, along with the faithful Captain Hastings, blunt Scotland Yard Inspector Japp, and hyper-efficient Miss Lemon.
"The Double Clue" is a bit of a tearjerker--jewels vanish, Japp's job is on the line, and Poirot is beginning to fall for one of the suspects, neglecting his job. Hastings and Miss Lemon attempt to salvage the investigation, but without Poirot they are going to have trouble. The end is sad, and this is the first of the Poirot shows to indicate that Miss Lemon might have more than professional feelings for her employer.
"The Mystery of the Spanish Chest" is a strange story about love, deceit, jealousy, honor, and lots of swords. A man is found stabbed in a "Spanish Chest"--and even Poirot is being checked out. This includes the excellent scene where Poirot, along with a friend, end up dancing the Charleston (with very bad grace)
"The Tragedy of Marsden Manor" is a particular favorite, with an elderly man dying unexpectedly and leaving a beautiful young widow who is being attacked by a ghost. The actress playing Lady Marsden is downright chilling at times, such as when she is staring up at the trees, and this story includes a man asking Poirot to proofread his mystery novel.
