Catwoman: Lonely City #4

Plot

ONE OF THE MOST ACCLAIMED BLACK LABEL SERIES EVER REACHES ITS CONCLUSION! All of the sacrifice-all of the broken bodies and shattered relationships-was leading up to this: Selina Kyle standing in front of the Batcave, desperate to know the secrets inside it, secrets once thought to have died with Batman. But you should never open doors you can't close-if opening them means swinging wide the gates of Hell!
