"The Strange Case of the Diabolical Puppet Master"
Synopsis
Batman is doing his patrol and sees a man bumping into another man on purpose. He interferes and the thug is driven away, but the other man, Dr. Craig, has a little scratch on his hand. Batman and Robin start investigating and find out something is wrong, so they go to Dr. Craigs house, where they find him hypnotized and handing over a secret formula to the thugs. Batman defeats the thugs and Dr. Craig comes to his senses.
The next day there is a scuffle on a train and the Batman is scratched on his cheek. That night, Robin finds out the Batman isn't in his bed and start investigating. Meanwhile, the police are trying to stop the Batman, who is robbing a jewelry store. Robin finds Batman with a bag full of stolen jewels outside the Puppet Master's house and gets slapped by the Batman. He hits back and the hypnosis is stopped. Batman enters the Puppet Master's house, still pretending to be hypnotized and surprised him by hitting him with a knock-out punch.
