Two mystery cases collide, as Batman gets closer to finding a missing socialite while Batwoman uncovers a gruesome new villain who has grafted knives onto his skin. There will be blood - and souvenirs of victims' flesh - in "Cutter" part 2!
And in The Question's co-feature, the unknown mastermind behind the gun-running scheme hires a professional killer to take care of some unwanted female companionship.
