This comic book details the origins of Batman’s Mad Hatter, a criminally minded man by the name of Jarvis Tetch who would be obsessed with an Alice of his own as well as bizarre millinery-based weapons and mind-controlling hats.
Perhaps what makes it most interesting is that we are very aware in the format of this story, all the information, all the tragedy, is being fed to us via the unreliable words of a madman whose dark imagination would make Queen Redd shudder in disgust.
