I read a mystery a few months ago where the detective was autistic. It was actually quite interesting, because you can see the areas where his autism helped him focus, but also where it limited his abilities. Near the end of the book, there’s a big scene with the bad guy, but the bad guy gets away for the time being because of some sensory issues. Anyway, it’s nice that it wasn’t all super convenient that he just happened to know about codes or Egypt or whatever.
