BATMAN (1940) #523

Batman must stop a frightening new rampage by the Scarecrow. Scarecrow escaped the newly rebuilt Arkham Asylum before all security measures were in place. He struck first while Bruce Wayne held a party for all three mayoral candidates. Batman contacted Bullock, who was able to confirm it was Scarecrow’s doings. He discovered a pattern and got to the next victim just after Scarecrow.
