From the page you directed us to, it sure sounds like a great book.
I will try to find it here in the US. I wondered when the reviewer got out of prison himself, he said he was in for life but he must have gotten out or he could not have met Healy. I wonder if he still plays now.
I found another site about Healy:

It has Leonard Bardon presenting some of his wins too.
