This episode is nearly a total failure. The murderer is obvious the moment we see him; he has otherwise no place in the story whatsoever. His motivations are ridiculous-- unconvincing and almost silly. When the two women closest to the main female character have been murdered, wouldn't the police have at least offered her some protection? But noooo.".. Not only are there no clues planted fairly to allow a sharp- eyed viewer at least the possibility of deducing whodunit, but NOBODY solves the mystery. The killer is caught because of an improbably civic-minded peeping Tom. Barnaby and Jones might as well have stayed home. These problems are not the fault of the cast, but of the writers and the producers.
