B.P.R.D.: Killing Ground #4

A mysterious monster is killing its way through the heart of B.P.R.D. headquarters, leaving the agents helpless as Liz withdraws further into the world of her visions. _B.P.R.D.: Killing Ground_ immediately follows _B.P.R.D.: Garden of Souls_. Written by John Arcudi and _Hellboy_ and _B.P.R.D._ creator Mike Mignola, and drawn by acclaimed artist Guy Davis, _Killing Ground_ brings the B.P.R.D.'s battle back to their own home.
