I read this story in an anthology in a school library sometime around 2000-2007. I don't remember the author, title of the story, or the title of the anthology, unfortunately. Description following is a bit gory. It was probably not newly published, due to the school's financial situation at the time--there were a lot of old/out of print books on the shelves and relatively few new releases
It was about a ghoul woman who looked like a living person and could pass as such. The story involved her escaping her grave, then essentially just looking around for dead bodies to eat. At one point she fell down a cliff, then had some difficulty getting herself back together as she'd broken her arm, though this was framed as an inconvenience rather than a source of pain. She eventually gets a job at a morgue, and there are various descriptions about how different types of death result in different quality meals (e.g., she mentions that drowning victims taste "spongey").
Turns out another employee is also a ghoul, and he reprimands her for eating at work and tries to get rid of her. She calls the police screaming, saying that her boss said he was going to kill her and put her in a specific drawer in the morgue. She hides herself there after intentionally reopening her injuries and playing dead, so when the police come, they find her just as described and arrest the other employee. They pull him out while he screams how they need to entomb her in stone instead of giving her a pauper's grave.
Does anyone know this story?
