As soon as she arrives in L.A., Mark remembers why he was happy not to see his sister Dora for years: she bosses him and everybody around like dogs and commandeers his bed while she stays in the beach-house till her new villa is fumigated against termites. Steve needed no reminder to keep clear, but that becomes impossible when her Realtor Harvey Wardell's corpse falls out of the closet, poisoned even before he inhaled a lethal dose. While Dora 'appoints' Genevieve Ducasse Harvey's successor, Steve locks them out of the murder-site and learns Harvey's secretary Lena Prosser is a gold-digger who filed a sexual harassment lawsuit against him, with exclusive access to his coffee, perfect to poison him, but anyone could have poisoned the spill-free mug in his convertible. Looking for Harvey's appointment book, Steve learns his young widow Constance Wardell isn't grieving for her philandering husband, but is already enjoying her freedom with a hunky personal trainer. Even Dora's nitpicking... Written by KGF Vissers

Betty White appears
27 October 2017 | by (United States) – See all my reviews

Betty White appears as Mark's fussy sister, and this episode is one of the few where the rest of the regular cast appear on-screen, where they have dinner at Mark's place. Diagnosis Murder has to be one of the best detective series and isn't afraid to tackle serious issues for prime time TV.
