Castle Full of Blackbirds

From 2023, this Dark Horse one-shot collects a pair of supernatural tales from the Hellboy universe, written by Angela Slatter and Mike Mignola with art by Valeria Burzo. The issue deepens the lore of the Bureau for Paranormal Research and Defense with a quiet, folk-horror story set in a remote Irish castle, showcasing the eerie, character-driven storytelling that defines this corner of the Mignolaverse.
