At the end of the previous Ellery Queen novel, "The Devil to Pay", he was in Hollywood and about to meet studio boss Jacques Butcher. At the beginning of this novel, he does so. Butcher, who is engaged to starlet Bonnie Stuart, hires Queen to work on a screenplay about Bonnie's mother, film legend Blythe Stuart, and her long-running feud with fellow Hollywood veteran Jack Royle. The two were once sweethearts, but their estrangement was bitter, and the feud now extends to their respective children -- Bonnie Stuart and young actor Ty Royle.
