Ellery must track down the killer of noted fashion designer, Monica Gay, who pulled the plug out of her clock and her TV set as a cryptic dying message. The three main suspects are Monica's financier lover, his jealous wife, and hot-tempered son who'd been having an affair with her himself. Each is charged and then cleared of murder but are they really innocent? Ellery must sort things through.
