Dr. Arkham's Observation Journal is a collection of Investigations that can be found within Arkham Asylum. There are 8 parts that comprise this set.


Gotham City has long since come to terms with the grim spectre of Arkham Island. Perched on the water like a contemplative gargoyle, this aging structure is the city's only barrier against pure insanity. The only person to truly understand the misanthropes and mad men that inhabit Arkham Asylum is it's head clinic: Dr. Jeremiah Arkham.

"Arkham Asylum is a laughably thin membrane keeping the madness away from the city's streets. You've gathered Arkham's notes, exposing more of his sickness. Diseased minds like his are why I will never rest in keeping Gotham safe."
