This book in its entirety is both humorous and serious in the right places. It should be read by any fan of SOE and certainly any budding cryptographers. It ties up a lot of loose ends in SOE history and should not be bypassed.
t was only after reading previous feedback for this company that I was decided. The product is second to none, easy to use and it makes a refreshing change to get something that works! Honestly, it does what it says.
