In 1929 Edward Doheney Jr and his personal assistant were found shot to death in the former’s opulent residence, Greystone Mansion. The official finding was murder-suicide: the assistant killed Doheny and then shot himself, but the facts just didn’t add up. Some dubbed it a lover’s quarrel; others blamed Doheny’s wife. Many suspected foul play as the two men had recently been called to testify against Doheny’s father in a bribery scandal. Greystone stages a series of interpretations of what might actually have occurred, using only dialog appropriated from Hollywood films also shot in the storied estate.
