In the novel Death Comes as the End, Henet was a female retainer in Imhotep's house. She hated Renisenb and her mother. In turn, most of the family disliked Henet too.
She found out who the murderer was, but was smothered to death before she could tell someone. She wanted to help the killer in murdering Renisneb, but while she was bragging to herself, the killer turned on her.
