The first story in issue #12 features one of the dumbest villains of the TV series, Marsha Queen of Diamonds. The first episode this character appeared in was neck and neck with the Archer episode as second worst episode of season two (the Black Widow episode being the worst), with one of the dumbest cliffhangers - Batman being forced to marry her. Unbelievably, this character was not negated to a one shot villain, and was brought back in a second episode... a three-parter, no less, but was basically reduced to being The Penguin's moll. With this issue, writer Jeff Parker has officially "jumped the shark". While his work on this series has been mixed, this story cements his legacy as a Charles Hoffman-Stanford Sherman disciple. The plot deals with Marsha tunneling into the Batcave, stealing the Bat-diamond, and the Dynamic Duo recovering it. Batman does some good observational detective work early in the story, but otherwise its a big disappointment, from D-list villain Marsha successfully breaking into the Batcave and stealing the Bat-diamond, to Alfred using a Bat-pole to go up into Wayne Manor instead of using the service elevator, to Marsha's Aunt Hilda's dopey magic and potions. Dario Brizuela contributes perhaps the worst artwork this book has seen. He really goes overboard drawing Batman as a pot bellied, out of shape slob.
