I really loved this story, certainly one of my favourite Pseudopod stories of all time, though I have to wonder, is that because it didn't really seem like a horror story? Sure, it had ghosts, and a serial killer, the danger of losing one's identity and ectoplasmic-testical interaction, but it could have quite justifiably been published by Escape Pod as the dark urban noir that it was. It's the more definitely horrific stories that tend to leave me varying degrees of cold.
In it's richness of texture it reminded me of the first time I read any of China Mieville's Bas Lag books, the little detail that is never explained but gives colour to the overall picture (like the Hamster Factor in 12 Monkeys). I'd definitely like a sequel, and this is one of the few times I've been so enthused by a story that I'm going to go visit their website to see what else they have.
