The British Black Coffee starred Austin Trevor in one of his many appearances as Agatha Christie's pompous Belgian detective Hercule Poirot. Adapted from a Christie play, the film takes place during a house party in a rural British mansion. A famous but much-hated scientist is killed, and several of his valuable papers are missing. The insufferably brilliant Poirot rapidly determines the cause of death and the motive. Narrowing down the suspects to the most likely culprit takes a bit longer-75 minutes, in fact. ~ Hal Erickson, Rovi
