The finale to B.P.R.D., Hellboy, Abe Sapien, Liz Sherman, and the
rest of the bureau face off against one of their oldest enemies in
the last battle to save the world. One enemy leads to another as the
B.P.R.D. finds themselves up against something--and someone--even
more sinister than they believed, and Christopher Mitten draws the
origin story of one of the B.P.R.D.'s most mysterious foes. Collects
B.P.R.D.: The Devil You Know #11-15.
