I'm looking for two picture books I read as a child.
The first I read in the late 90s, but it might've been (much) older. The story involved a woman being kidnapped by a winged monster who later turns out to be literally heartless (IIRC there was some system similar to the Harry Potter horcruxes where the monster's heart (and possibly some other body parts) where placed somewhere outside of his body, and he was immortal until his out-of-body-heart was destroyed). The monster's death featured a surprising amount of gore.
The second picture book was one I read in the late 90s and featured a story about a group of monsters living in a house together. The monsters leave the house one night and another monster comes out: he's a monster that's hated by all the other monsters. He explores the house. The picture book was quite dark and creepy as far as picture books go.
If anyone recognizes one of these I would be extremely grateful.

Waiting for a "thank you" at least, pal.
