The Greene Murder Case (1929)

This all starts with a sort of roll-call where a lawyer checks the presence of the "Greene" family at the bedside of their mother. A condition of their late father's will is if they don't all live together for fifteen years after his demise, then they don't get a sou. Not surprisingly, they don't exactly see eye to eye so when one of them is shot, it's hardly a shock. The police - the instantly recognisable Eugene Palette as "Sgt. Heath" - duly arrive and enlist the help of detective "Philo Vance" (William Powell) who quickly discovers that any one of them could have done it. Thing is, the killer isn't content with just the one - and when the family start to drop like flies, the investigators must get a move on in case it is just them who are actually left at the end! It's very stage-bound, this, but the pace is break-neck and there are a few characters - not least the bed-ridden and grumpy mother (Gertrude Norman), to keep the investigation moving along until it's slightly unexpected conclusion. It's a bit of an hybrid of other "Dark House" style stories, but Powell and Pallette deliver simply and quite well here.
