Head Cases by John McMahon

 

Apparently this is book one of a series, possibly a trilogy instead of something indefinite (the author has done a trilogy before, though I don't know how planned). This is a decently-written procedural-ish novel, a bunch of FBI agents matching wits with a very smart serial killer (which has a specific meaning in law enforcement, and is used correctly in the novel despite a putative psychologist apparently refusing to accept it as a term) but it's all told from the point of view of an agent who is somewhere on the autism spectrum, though he apparently functions at least mostly OK in society; he's an interesting narrator, both as a character and as an authorial decision. The other characters are pretty clear and relatively believable (given the inherent plausibility problems with the sub-genre); most of the twists and reveals were adequately foreshadowed, so it didn't feel like endless "no it's another twist" thinking it was clever. Pretty decent, but not anything I feel a need to read more about.
