Between Good and Evil is Roger Depue's retrospective look at a life spent apprehending criminals - mostly serial killers - as a small-town police chief, Swat team member, Behavioural Sciences Unit chief and developer of revolutionary law enforcement programmes that were the precursor to VICAP. The book also charts a spiritual odyssey that culminated in Depue becoming a Brother of the Missionaries of the Holy Apostles. While a seminarian, he counseled maximum security inmates. Following his time in the clergy, he re- entered law enforcement and today heads up the world's most elite forensics think tank, The Academy, which was the basis for the Chris Carter-created Fox TV show Millennium.
