Re-reading this was enjoyable, especially given that I had been thinking a lot about Lovecraft (with running Trail of Cthulhu) and it's relationship to espoinage fiction (given the Delta Green connection in my game). Plus, I've been reading a bit of Hellboy/BPRD and thinking a bit about Cold City/Hot War too, so I guess the whole apocalypti/monsters from beyond thing might be rather on my mind right now.
Anyhow, to the book itself... it's certainly raw compared to his later work, and filled to the brim with nerdy jokes about Lovecraft, information technology and spy fiction. Still, they are good jokes and it is a good story. I suspect that The Jennifer Morgue will get a second read pretty soon, too, and I'm looking forward to the third outing even more now.
