I tend to avoid books about Everton - the Southall and Kendall autobiographies excepted - but this one seems so well sourced that it would be remiss to ignore.
The problems with most autobiographies is that they are self-serving. People compromise themselves to avoid offending others if they think it's in their interests to do so. But with so many varied perspectives of something like the Ferguson transfer, you get a much more balanced impression to add to your own.
Johnson was a charlatan. Yet, I don't think his successor was any less of a chancer, despite his Evertonian credentials. PJ spent a few quid, realised he didn't have it, panicked, and then fled. It's almost funny. Bill would never have to panic as he never spent a bob.
