B.P.R.D.: Plague of Frogs #4

Liz Sherman is set upon by a cemetery full of fungus-driven zombies, and Abe Sapien uncovers the connection between this new generation of monsters and the B.P.R.D.'s old enemy Rasputin. But as the frogmen begin their rituals to raise the old gods, one of the disciples makes good on the threat Rasputin leveled against Abe years ago in Hellboy: Wake the Devil.
