Books like Abraham's Boys: A Story from the Collection 20th Century Ghosts

An interesting spinoff of Dracula that explores the mentality of Abraham Van Helsing. It portrays him as a senile old man that has trouble distinguishing reality from fiction. He drags a woman into his basement believing that she is a vampire when she’s really just an ordinary woman in extremely poor condition. It makes you think. Were the people he killed in his past really monsters or were they just normal people that were disfigured by poor health conditions? Sickness and mental health were treated very harshly in the past so it wouldn’t be out of the question. Perhaps he’s not such an honorable hero after all, just another ignorant man that was possessed by an irrational paranoia for things he didn’t understand.
