"It is the House on Haunted Hill. It is the Last House on the Left. It is the place that Batman's most dangerous and psychotic villains call 'home,' and you are cordially invited to spend 24 hours within its walls. Welcome to the Arkham Asylum: Madness, 97-page special where readers will live and move and walk among the nurses, doctors, security guards, and inmates. It takes a special type of person to end up here, no matter what side of the law you're on, or what your job is. For when the midnight hour approaches, all hope is abandoned and inmates and workers alike will wish for the daylight-- and for their sanity. Pray you get out before the darkness comes. Pray you get out before your shift is over. Pray that you do not go mad" -- dust jacket.
