A man trapped behind a wall calls on Hectate and binds her to do his will. Hellboy’s horns, broken off by him in a previous story, are recovered for some unknown purpose. And Hellboy, drinking by a fire safely at a friend’s home, mourns the loss of his mentor. When he goes for a walk, the action begins. And thus starts Darkness Calls, expertly drawn by Duncan Fegredo and colored by Dave Stewart.
