Birds of Prey(1930)
Adapting A.A. Milne’s play The Fourth Wall, this tense thriller is among the earliest films produced at Ealing and stars C. Aubrey Smith as a former police commissioner who becomes the target of a revenge plot. At a reception given by Arthur Hilton at his Sussex home the conversation turns to the subject of danger, with Hilton recalling a case in which he was involved as a Natal police commissioner. In it there were three guilty persons, but only one of them was hanged; the other two were sentenced to long terms, vowing vengeance on Hilton. Unknown to him, the same two men are now among his guests, and are determined to have their revenge.
