The Surgeon of Crowthorne
Excellent little book. Only 200 pages long, so easy to get through. The Oxford English Dictionary was the result of thousands of volunteers sending in definitions of words, along with their first known usage in literature. One of the most prolific contributors was William Minor, a surgeon who hailed from America. James Murray, the editor of the OED, invites Minor to various shindigs to celebrate the release of each new volume, but he never shows, despite only living an hour away by train. Curious to meet Minor and thank him in person, he travels to Crowthorne and discovers that the doctor is an inmate of the Broadmoor Criminal Lunatic Asylum, having murdered a man 20 years earlier.
The two become firm friends, bonded by their shared love of literature and language, and the book does a great job of hopping back and forth between their life stories and the travails that led them to cross paths in the first place.
Highly recommended.
