The Batman & Scooby-Doo! Mysteries, Vol. 1

One or two monster masks might just mean there's a smuggler or crooked real estate developer in town. But when Gotham City is terrorized by an army of thugs in monster masks, it can only mean one thing: a citywide crime spree by Black Mask and his gang, the False Face Society! With Batman mysteriously missing, and Nightwing and Batgirl up against a horde of crooked creatures, it's lucky that the heroes have help from Scooby and the gang. After all, who has more experience in pulling the masks off bad guys?
