Stirling Deane has sold the Little Anna Gold Mine which he discovered in South Africa early in his career. The sale has made him a rich man and the head of the company to which he sold the mine.
Deane is threatened with ruin when a old enemy Richard Sinclair- shows up in London with what appears to be a legitimate prior deed to the mine. Another man which Deane hired to negotiate the return of the deed to Deane is accused of the murder, tried, and sentenced to death.
