Vampire AU

[sostrangechild.livejournal.com]

So I've had a good look around, but my Internet-Fu has failed me once more!

The story I'm looking for is a vampire AU, set in the Victorian verse (09!verse possibly), were Watson has been captured by vampires and they're holding him hostage. When Holmes tracks them down, they give him an ultimatum - Watson dies or Watson is converted. I think Holmes may have been recently turned, but I'm not sure on that bit. I read it around the end of last year, if that helps.

Thanks all!

P.S. I'm posting on my phone, so I can't get all the tags - will rectify in the morning!
