"Past Reason Hated," by Peter Robinson, differs from the run-of-the-mill murder mystery. Inspector Banks, who is the sleuth in this series, is always fascinating. He is a chain smoker who enjoys drinking. He loves classical music, although he is not overly intellectual. Banks truly shines in his ability to communicate with suspects in a murder investigation. Banks is the best interviewer in the business. He has unerring intuition when it comes to spotting lies and evasions, and he has a way of getting people to reveal a great deal of themselves. Most of all, he cares about seeing justice done, no matter how long it takes and no matter whom it may hurt. In this novel, a young amateur actress named Caroline Hartley is found brutally murdered. She has had a tumultuous life, and any number of people might have had reason to kill her. Banks interviews those who knew Caroline years ago, as well as those who were closely involved with her shortly before her death. "Past Reason Hated" deals with such themes as struggling to come to terms with one's sexuality, the fears that cause people to commit irrational acts and the complicated and inexplicable nature of human relationships. "Past Reason Hated" is an engrossing and satisfying psychological mystery.
