For a novella, this one was pretty good. It was interesting to see the characters from The Restorer making cameo appearances, and it was a different take on the whole idea - following a person who is haunted by a ghost rather than one who is able to see ghosts. 
 That said, parts of it felt very rushed. I got the creepy feeling again during certain scenes, but I was never so drawn into the story and the creepiness lingering behind it that I just had to read on. I could, and did once or twice, stop reading and only return to the story a couple of days later. There was no chance I was going to do that with The Restorer, which I finished in mere hours. 
 So, all in all, good but not great.
