Hastings is invited by his friend Charles Arundell to be at hand when he tries to break a water speed record on a Berkshire country lake, but his boat's engine fails him. At a subsequent reception at the estate of Charles' well-to-do aunt, Poirot and the other guests witness her refusal to continue to underwrite Charles' expensive hobby, and he threatens her. Later, when she is almost killed in a freak accident involving her pet fox terrier Bob, she confides to Poirot that she suspects a family member of trying to kill her to gain part of her estate. The detective advises her to disinherit her grasping relatives and name a friend as beneficiary. Despite this precaution, she dies abruptly under questionable circumstances, but the local authorities refuse to authorize an autopsy. Suspecting foul play, Poirot looks to his wits as well as the Arundell dog, who remains a silent witness to murder. Written by G. Taverney (DUKE1029@AOL.COM)

Eerie Christie story filmed amid fine trappings...
27 August 2010 | by (U.S.A.) – See all my reviews

This is a delightful version of a rather unknown Christie story that deserves recognition as one of her most clever entries. I was partially successful at guessing the solution and once again it's a trick that Christie plays on her audience, this time involving a very subtle clue.

David Suchet and Hugh Fraser (Poirot and Captain Hastings) are vacationing in the English countryside near a wealthy woman's estate when the lady of the manor reveals that she suspects one of her heirs is willing to kill her in order to amass a fortune. From then on, it's up to Poirot to solve the case, based on what seems like very flimsy evidence involving inspiration from a dumb witness--a frisky fox-terrier named "Bob." The usual suspects keep their secrets well hidden until the final denouement which may come as somewhat of a surprise to most viewers.

A very eerie death scene involving a green mist that envelops the victim is stunningly staged for maximum effect. Well done mystery makes good use of a fine cast of players.
