The play - a slender plot revolves around the shooting of the leading man. But when the show opens at the Grosvenor Theatre to a packed house, Brandon Baker is killed by a real bullet. When another member of the company is found dead, initial appearances suggest a straightforward case of murder followed by suicide. But there is, of course, more to it than that. The audience includes Inspector Wilson of Scotland Yard and his son, an enthusiastic young reporter.
