The cover is atmospheric and engaging in an old-timey Enid Blyton type of way, and the opening chapters mark an intriguing beginning to the next installment in the A Bletchley Park Mystery. It’ll be interesting to see the kind of work that Ned and Mrs Letton end up doing—and how it ties in to the espionage that is bound to be going on and to the apparent anti-Jewish sentiment. It’ll also be particularly good if Mr Letton and Harri get the respective comeuppances. Hopefully Robyn and Mary will show up at some point too.
