"The Cat's Meow"
Catwoman is released from prison, and seems to have reformed. Even Commissioner Gordon believes her, inviting her band to play at the Police Benevolent Society Ball. But she is actually conspiring to steal the voices of British singing duo Chad and Jeremy, who are boarding at Stately Wayne Manor.
She disguises herself as a dance teacher to get inside the house and learn its layout, though why she needed this is unclear since she never returns. She does steal some important voices, however, including that of Commissioner Gordon's!
Gordon and O'Hara say what everyone's been thinking, when they comment on how Batman makes their jobs easier.
What will Catwoman do with Batman's body once his mind's been erased?
