Just as Zelda's deadline is about to expire, Bruce Wayne, Commissioner Gordon and Robin arranges to deliver the ransom money through live TV and manage to convince her the money she heisted from the bank was real. When Aunt Harriet is returned from her captors, a matchbook advertising Ekdal's Gnome Bookstore falls out of her pocket. This clue Zelda hopes will lure The Dynamic Duo into her trap. Batman and Robin speed to Eivol's Bookstore, where they fall prey to Ekdal's Inescapable Doom Trap, a large transparent cage made out of Jet Age plastics. When deadly gas fills the cage, The Caped Crusader ignites it by placing his metal utility belt buckle against the electrified grating at the cage's base, causing it to blast open the door and releases them.
Zelda, who has borne witness to the affair from Ekdal's hidden room, feels guilty and warns Batman and Robin about the gunmen hidden inside two mummy cases just outside The Doom Trap waiting to blow them away. The Duo quickly duck out of the way just in time to avoid the gunmen's bullets, which insidiously do them in. Eivol Ekdal tries to make a break for it but is stopped by a well-aimed Batarang tossed at him and moments later, a wet-cheeked Zelda quietly surrenders. Ekdal is put away and Zelda, having helped save Batman, gets a reprieve and a job as a children's' magician.
