Comments:
This story introduces several new elements to the "New Look" Batman. Batman has redesigned the Bat-Cave with an automatic elevator leading to Wayne Manor. The Batmobile has also been redesigned into a sports car. The Bat-Cave exit is no longer a barn, it is now a hidden door on a hillside and leads to the highway.

Batman also uses a Hot-Line phone which links the Batmobile (later the Bat-Cave too) to Commissioner Gordon's office. Gordon's physical appearance also looks younger and slimmer than prior appearances.

Synopsis:
After showing Dick Grayson the new modifications to the Bat-Cave and Batmobile, Batman discovers a criminal plot to divert a group of folk singers from reaching their destination. The singers are diverted by a man named Dabblo who has planned a robbery for the same time the singers were to perform. By delaying their arrival, Dabblo prevents a crowd from forming which would hinder his escape.

Dabblo pulls off the robbery of a valuable pearl successfully. Batman and Robin follow his trail across the rooftops. Dabblo has a trap planned for Batman, but the Caped Crusaders avoids it. Batman then captures Dabblo and returns the pearl to the museum.
