E. W. Hornung 
Crime Doctor 

Author E. W. Hornung is perhaps best remembered for creating the unforgettably raffish criminal mastermind, Raffles. In the novel The Crime Doctor, Hornung flips the script and takes a hard look at crime from the other side of the equation. Doctor John Dollar is a learned scholar and practitioner who becomes obsessed with the idea of preventing criminal behavior before it takes hold — and he’s willing to take extreme measures to fulfill his objective.
