Boxer, Beetle by Ned Beauman

This book is not quite in the same league as The Teleportation Accident, but it was still a great story. It features Kevin, a collector of Nazi paraphernalia who makes most of his friends on the Internet because he suffers from trimethylaminuria. When Kevin finds a letter from Hitler to a British entomologist, he finds himself rushing to solve a seventy-five year old mystery with very real implications. The complicated plot was handled very deftly, and I thought the story, filled to the brim with flawed, unhappy characters, worked very well.
