I'm glad magnetic_pole has looked up Dolohov so I didn't have to; I couldn't have placed him, either. The more kudos to you, as you made a character come alive who, to me, has been merely a name in canon. The background you give him is intriguing, his isolation, his relationship with Igor, his affiliation with the Death Eaters and with the Black family - every step he takes (or is pushed into taking) in his life is calculated to break him down bit by bit, to mould him into a cog in an efficient and destructive machine. With his love for Narcissa and his relationship with Draco, he is almost a mirror-version of Snape.
