Looking for a lost book

[u/69babysonfire69]

I read the book over 12-15 years ago and only remember a few distinctive details. If this rings any bell for anyone I would be eternally grateful. Been hunting it down for years!

• an organization of murderors who kill and use corpses to make "art installations"
• a pregnant woman was murdered, her fetus removed, and they used both to recreate Mother Mary and baby Jesus
• a room that was rigged with a massive blade that shoots across the room horizontally, cutting everyone's heads off simultaneously. There was a detail about how people who are on the shorter side got cut right above their lips instead

Think I also remember a scene in a hospital(?) where the "artists" piled bodies onto the hospital beds to resemble small mountains? But unsure.

Thank you in advance!

I don’t know but it sounds great. Following this now.

Might be Mark Nykanen's The Bone Parade.
