John Podmore appeared on BBC Breakfast this morning and has since been racing up the Amazon charts. An excited email from Biteback MD and all-round big cheese sent at 14.44 this afternoon showed Out of Sight, Out of Mind was leaping up the bestsellers list.

A little further delving from yours truly showed that Out of Sight, Out of Mind is NUMBER 1 in Amazon's 'Movers and Shakers' chart.

Yeah, you know, we move. We shake. Whatever it takes to get important books sold. All this has caused a bit of a storm on Twitter too. One prison worker tweeted:

'I spent several years working in prisons. This book will set much needed changes in motion.'

We can only hope.

John has governed at three British prisons, most notably HMP Brixton which he took from being Britain’s worst performing prison to being its most improved, so if anyone knows how to do it, he does!

Out of Sight, Out of Mind is available now, priced £14.99. If you're still not sold on why this book is so worthwhile, listen out for John Podmore on Start the Week next Monday at 9am and 9.30pm.
