Query: a moving account of very meaningful work

Dr. Roberts' description of the prisoners with whom he worked was sensitive and empathy-provoking. His ability to connect with people whose background and experiences were so different from his own was truly respectable. His keen perception of the rehabilitation potential in the most rough and violent people is inspiring to others who work in helping professions. The story itself was fascinating; Dr. Roberts kept me really interested in the characters and what was going to happen next.
