Great Diamond Mystery Synopsis

Ruth Winton, author of The Great Diamond Mystery, tests its hypothesis--that a murderer will return to the scene of the crime--when her sweetheart, Perry Standish, is sentenced to death for the murder of his employer, Graves, a diamond merchant with underworld connections. Ruth rents Graves's house; rehires Davis, the butler; and notices that Mallison, Graves's partner, snoops around the house for some missing diamonds. In the climax, the butler is shot and makes a dying confession to Graves's murder; Perry is pardoned at the last minute.

Confidence artist Flossie Golden attempts to fleece foolish but wealthy James Venable with a breach-of-promise suit. Venable's shrewd attorney, Richard Harding, outwits Flossie by proposing that she marry Venable and live on an allowance of $3,000 per year. Flossie is determined to get even with Harding for ruining her plans. In an attempt to con him, she poses as Innocence Page, but falls in love and marries him instead. Larry, Flossie's former accomplice, endeavors to blackmail her with her errant past, but Harding is already cognizant of the facts and Larry fails.
