The full title is The Professor and the Madman: A Tale of Murder, Insanity, and the Making of the Oxford English Dictionary. Honestly, that covers just about everything you need to know. If the title intrigues you, you’ll enjoy the book. If the mentioning of the world’s largest dictionary turns you off, don’t bother.
Most of the time I was reading this book, I had also had two little dogs crawling over me trying to get attention. The writing was engaging and clear. I could put it down whenever I needed and never had a problem picking it back up.
