A self professed 'vampire chaser', in 19th century Paris. He claimed evil was clever beyond most men's comprehension. He seemed to have been a true believer. He combined the infant science of forensics with his beliefs, however, and with fiber samples provided by MacLeod, he declared that "Nicholas Ward is a vampire, now we've proved it, now I can destroy him."
He ambushed Ward, knocked him out, doused him with holy water, and drove a steak through his heart. Ward, revived, however, and then killed Baines with the same stake through his heart.
