Gordon Webster narrates, and short-form non-fiction lives or dies on that choice, since an hour and twenty minutes leaves no room for a reading that drags. No listener verdicts have landed yet, this being a recent addition, so there is no score to lean on either way.
The practical case for it is the running time. It fits a commute, a long walk or an afternoon of ironing, which makes it a low-risk way to test whether the argument lands with you before anything longer is worth your while.
Have a look below and judge for yourself.
