I need help finding some really great authors who take their writing seriously enough to allow the reader to learn as they read. I am interested in deep psychological thrillers that combine knowledge of abnormal psychology, respect of the super-natural or unknown ways of nature, and crime. Does anyone have any suggestions? Really good non-fiction books on the whys and wherefores of inhuman behavior are hard to find...at least authors who take into consideration as many valid explanations as apply to the situation.
