I got this book as a support to research I was conducting into the Right Club and Captain Ramsay. I found Joan Miller's story to be interesting and surprising. It seemed to me that the British intelligence service was a hotch-potch of people whose greatest claim to be included was that they were schoolboy mates of someone already an agent! Few seemed actually to be talented in spying or spy-catching! The few that were, were clearly very clever people indeed, that must have made the difference. Many were closet homosexuals, at that time illegal, and knowledge of their proclivities by the enemy would have made them ripe for blackmail. It makes you think that the German intelligence service must have been every bit as inept, otherwise I cannot see how MI5 would have had any success at all! That said, there are some interesting anecdotes in the story. I enjoyed it, anyway.
