Angela Lansbury's former MGM colleagues Van Johnson and June Allyson are prominently featured in this episode. A double-dealing businessman is killed when he is run over by a remote-controlled station wagon. Suspicion immediately falls upon the victim's disgruntled former partner, an oddball inventor--who happens to be a neighbor of our gal Jessica Fletcher (Angela Lansbury). Can it be that the death car's curious license plate number will turn out to be a clue? (Well, maybe not.) ~ Hal Erickson, Rovi
