I must confess, Jock was the father of a close friend, so my review is highly biased.
Jock was a scientist by profession, and while I imagine he wrote for journals, he wasn't a writer for the popular press, nevertheless he was a story teller, and Tangled Tongue is his story of living with a stutter, and how he overcame it - and didn't. It's a fascinating story of what was known at the time about stuttering, and the many techniques — some successful, some not — that Jock and others have used to surmount their handicap.
