Here's my first draft of how my character works.  Feedback welcome.<br/><br/><strong>Chase Lawrence</strong>is originally from Westport Massachussetts.  In his youth he was an athlete rather than a fighter: long-distance runner.  He likes puzzles.  He was a philosophy major, specializing in  meta-philosophy, the foundations of knowledge.   His graduate studies were interrupted by FBI recruitment.  When, after the usual apprenticeship here and there, in Delaware then upper New York State, he was attached to a unit specialising in sexual crimes, he was upfront about being a sado-masochist himself in his private life.  His boss, a woman called Serena Maitland, said she already knew: that was why she'd recruited him.  He was instrumental in bringing the original killer to justice.  Afterwards he had a breakdown; he feared there was something about him that brought him too close to such a mind-set.  But he recovered, returning for a while to work on more routine cases, till the emergence of the copycat killer meant he was returned to his old stamping ground.<br/><br/>Chase is divorced, but friendly with his ex-wife Shaz, a lecturer in anthropology at the Univ of Pennsylvania.  She lives with their teenage son in Philly and Chase tries to visit often.<br/><br/>He's good-looking in a wry sort of a way, with an upper right drift to his mouth, and grey-green eyes.  Tall, still athletic.  In idle moments he's usually doing a complicated arithmetic puzzle.
