Dark Horse Comics released Hellboy in Love: Black Eyes one-shot last week. The cover is by Alex Nieto and the script is by Mike Mignola and Christopher Golden. Here is the official summary:
"A cozy visit with retired B.P.R.D agents Archie and Margaret takes a chilly turn when Hellboy and Anastasia investigate the local ghost, whose once only legendary wails have been disturbing their quaint village with more and more urgency."
