From Acorn TV:

Reece Shearsmith stars as DS Sean Stone, who has an uncanny ability to identify and predict patterns of human behavior. He knows how people work, but he doesn’t understand them.

Welcome to another “Eccentric Detective” TV Series. Most certainly DS Sean Stone must lie somewhere on the Asbergers-Autism spectrum.  In fact autism in a person often exhibits as extreme ability with patterns coupled with a corresponding inability to understand human emotions.  Needles to say his lone wolf behavior and air of infallibility drive his colleagues to puzzlement,  anger, and exasperation whereas his pattern recognition abilities earn respect.  His superiors want to get rid of him while some colleagues defend him.

Good plots, good acting, and an unusual detective make for compelling entertainment (as long as you don’t mind a nasty serial killer or two).
