Mark Sullivan

Mark Sullivan is an undercover police agent posing as an associate of Johnathan Taylor. He features in The Death of Johnathan Taylor.

The criminal fraternity that inhabit York are a higher class of villain. They don’t go in for such troublesome dealings as mugging, robbery or kidnap; rather, they are white-collar crooks who carefully extract their thousands from unsuspecting businesses and insurance firms, never getting their hands dirty, and rarely drawing attention to themselves.

However, they do form a very definite fraternity. Many of the most profitable schemes require several people to pull off, and so each of the most prolific criminals keeps a book of contacts to draw upon, forming a loose network of crooks centring on the eccentric, brilliant and notorious Johnathan Taylor, who has been implicated in a score of crimes but who always manages to evade conviction.

It has been the focus of covert police attention for some time, and, recently, the force succeeded in placing Mark Sullivan as an undercover agent into Taylor’s circle. He has been tasked with building cases against the other member’s of the group while remaining hidden yourself, but in Johnathan Taylor’s brilliant and well-paid company, though before Jonathan's death he was beginning to wonder whether he might not be better off if he were to join the great man in his work.
