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)

At the end, when Charles Arundel states that he's leaving water speed records to "Campbell and his cronies," he's referring to Malcolm Campbell (1885-1948), who set several land and water speed records. In his craft "Blue Bird K4" his highest water speed record was over 141 MPH, a mark reached in 1939. See more »

Poirot and Hastings at the top of their game!
11 June 2011 | by dan.adamsSee all my reviews

All episodes should be as entertaining as this one.Fortunately the majority are! Things are never as they seem-as usual.As Poirot might say,"when there is a cry of "Fire"-quite often it comes from the miscreant who lit the match".And so it is with murder,n'este ce pas? Look for the person who first claims dirty work! Also,look for the suspect(and aren't they all?)who conveys a piece of vital information to the eager ear of the murderer-who seems quite trustworthy at the time. Don't you love the Lakeland?I've been on the train that Poirot and Hastings rode-also the ferry.Great stuff that adds touches of realism to this delightful tale of crime in the most genteel of places.Thumbs up!
