Police Comics #25 (1943)

Woozy decides to buy a book to help him stay in at night and control his impulses. However the proprietor of the establishment proves to have been knifed in the back. Woozy calls Plastic Man to report the murder, but before the partners can meet up, Woozy's shoved into the back of a car by a pair of rough types looking for something. Arriving at the book store, Plastic Man sees a regular man emerge surreptitiously from a secret passage and seize a package, but when he tries to find out what the man's after, the lights go out and he's been knifed too. At the hideout of Woozy's kidnappers, they mention they think he's someone named Simpkins, there to sell a valuable book. The real Simpkins shows up to make the agreed upon exchange, but Woozy takes advantage of the distraction to purloin the book and make his getaway. He runs into Plastic Man, who catches Woozy's pursuers, but then the heroes find themselves held at gunpoint by the sinister masked Number Seven. Someone who was disfigured in WWI, and unable to show his face in public, his only joy is in collecting rare books, like the one the others were sent to collect for him. However he's so distraught when he realizes all this has been, not for a copy of "The Life of Thomas Quince" but "Quinn", Seven is so distraught he loses the will to fight. Ultimately it turns out Woozy had the book Seven was after the whole time, disguised as a low-grade mystery novel that'd appeal to his salt-of-the-earth sensibilities.
