Detective Comics #434

Gotham's criminals are aided by The Spook, who employs apparent mystical powers to facilitate their escapes. After a criminal breaks out of a new maximum-security prison, Batman and Commissioner Gordon intensify efforts to apprehend the culprit. The Spook's advantage lies in tracking devices he provides to criminals, enabling him to locate and assist them. Batman, deducing the use of tracking devices, disguises himself as a criminal to confront The Spook. Surrendering and activating the tracking device from prison, Batman anticipates The Spook's intervention, setting the stage for a face-to-face encounter.
