I only just heard of him myself! He is a creation of author C. S. Harris and you can investigate him and his creator more thoroughly at http://csharris.net/
The viscount is the damaged, enigmatic hero of a series of very dark Regency-set mysteries, and I'm in love with him already. I just finished reading "What Angels Fear" and it was excellent. The Regency world that Sebastian inhabits is very different from the Regency world my characters live in. But it did exist, and Ms. Harris has given it an authentic feel. If you like a dark mystery (warning: lots of violence and dirt), you will find this series intriguing. I don't usually read anything like these books, but I found this bleak underbelly of the Regency fascinating. I think it is important for me, to give my work credence and authenticity, to be very aware that this other side of London and its society existed.
On another note entirely, some very good writer friends of mine have just started their blog. They are going to cover all kinds of topics of interest to writers, and I may show up there occasionally as a guest blogger. Check them out at Prairie Chicks Write Romance http://www.prairiechickswriteromance.blogspot.com/
