The Take-Away: Even though the math was over my head, the discussion of it
The two plots don't cross. Jericho doesn't need the missing Claire to crack the code, and it only side tracks him a bit. A very minor plot point was overlooked when Jericho contradicts his supervisor in front of the Americans. It's a temporary conflict that wasn't exploited to the max. I would have rather seen that then all of the doings with Claire.
Recommendation: Good, if you like historical thrillers.
I definitely felt the frustration of code
Entertaining, informative, a good recreational read
Firstly, it seemed a huge concern, far more people involved than I had been led to believe.
I’m a fan of Robert Harris but found this slow moving. And I found the ‘thriller’ element simply a tool to illuminate the (well-researched) work carried out by cryptographers at the Park during the war years. So, 4*s for shedding light on Bletchley’s role in the 2nd W.W. for civvies like me.
He uses fiction to dramatize the story having the British Intelligence force place a
Mainly a fast moving mystery that is a gripping read.
