True Crime is surely the hottest genre in the country at the moment. All three big TV networks air weekly programs devoted to it, and the top podcasts are, and have been for a while, true-crime stories.

But what about the people who know best about the subject? We wouldn’t have this content and, more importantly, society couldn’t have put away so many killers, if it were not for their efforts.

A new Hulu series specifically highlights an authentic pioneer; Dr. Ann Burgess is an unassuming woman of a certain age now, but she was a true innovator in the field of profiling and studying the common threads among victims, not just perpetrators. We’re talking pre-Clarice Starling, although she did work with Jack Crawford, the FBI agent played by Scott Glenn in The Silence of the Lambs.

Mastermind: To Think Like a Killer goes one-on-one with Dr. Burgess as she details the fraught road in the early days as the only woman in an office of male agents, and guides us through some of her more infamous and/or interesting cases.

Make no mistake, this isn’t a retread of the Netflix hit show, but Mastermind does sketch some of the cases upon which the show based its true story episodes. No, this is really Burgess’s story more than anything. In the days before DNA, the job of profiling was more art than science, and Burgess, a psychiatric nurse, knew that better than anyone.

She had to be smart, better, and show no-nonsense leadership to get such a large, stagnant mountain, such as the Bureau, to move and change its ways-look at things differently

The unprecedented access to the development of modern serial-killer profiling is spread over three episodes on Hulu, starting July 11th, and if you think of it as more a Master Class than a stand-alone entertainment, you’ll enjoy the history behind this most popular of subjects.
