Tyler feels at last.
This series about an extremely intelligent and autistic orphan detective of 9/11 has been a joyous, if sometimes arcane ride for math/logic lovers who focus on their mysteries without the necessary adornment of "relationships." The deepest relationship so far for Tyler in the entire series has been with his shelter-adopted dog and herein it comes to a conclusion. In fact, this is more his mystery to solve than the murder needing resolution.
Tyler is out of place in the southwest, opposite in almost every way to Lake Saranac, New York, and apposite in almost every way to the needs of the emotionality of the theme of losing someone Tyler really loves and facing it with the depth of support provided by the kindest of strangers - the Navajo. We have the opportunity to feel one of our most human pains through the lens of autism and it hurts even more for Tyler's inability to express or comprehend what is happening in his heart. Sheffield expressed it tautly, thoughtfully and thoroughly without having Tyler's personal Asperger's contorted understanding/misunderstanding of someone previously unable to analyze/formulate/mathematically calculate a feeling, let alone such massive ones as love, loss, friendship, care, social notes for kindness.
Sheffield has a great future writing and much to say as he learns from his students. His grammatical/spelling errors are seldom and/or small, but irritate me because he is a teacher. However, because he is, on the whole, an excellent teacher, I am willing to chalk those up as computer over-rides as I often encounter them myself after they have conspired to make me look and sound sillier than I usually am. Good on, Professor, good on.
