It's 1943, the war is raging, and sleuthing scribe Ellery Queen wants to do his bit. After a tortuous cross-country drive, he takes a job writing scripts for a Hollywood propaganda house - twelve hours a day of hack work that quickly turns his mind to jelly.

Or had some past scandal driven lawyer Ollie Hurst and his wife, Norma, to claim the blackmailer's life? Dave Tully didn't know who the killer was, but if he didn't find out fast, the price of failure could be death....

The nine-word clue was one of nine cryptic notes that had been sent to taunt Inspector Queen and his son Ellery nine days after the murder. Nino Importuna had been obsessed with the number.
