Mark Pilkington’s book, based on evidence from the UK and the US, will force you to confront the awkward truth that buying stuff online from your sofa or office desk threatens not only town centres, but also the jobs of the seven million people who work in shops and the industries that depend on them. Worldwide, about 192 million jobs — most of them held by women — may be in jeopardy. Retail Therapy bristles with alarming numbers. It can sometimes seem as if Pilkington, a retail consultant, made a bulk order to a data wholesaler (Scary Stats R Us?) to support his treatise on the downfall of BHS, Toys R Us and many others.
