Lots of TLC on display here in terms of narrative and photos. Full marks to the author, publisher and all involved. A fitting tribute to the incredible work done by the folks at Bletchley Park. I loved poring over the many photos which catapulted me back to those halcyon days - as the author comments, working there was a most thrilling and life changing experience for those involved. How sad that they were prevented from describing their days there for so many decades: most passed away without ever talking about it, true to the last to their promise not to. For every Bletchley fan this book is a must. And pay them a visit if you can - I've been there twice and it's an amazing experience!
