Stories by award-winning author and game designer Dennis Detwiller.

These tales of cosmic terror and personal horror span the life of Delta Green, the desperate organization that Detwiller helped create: a group of men and women who have seen the awful truths of reality and struggle to keep those realities at bay as long as they can.
