Its possible my low expectations have resulted in this high mark but i'm not sure. Its a very solid spy-thriller. With a few touches of women vs male authority. I actually would have preferred if Worrals was a little older as being 18 lends an extra YA element to proceedings too, which was unnecessary.

These kind of spy adventures can be very convoluted and messy like the awful [b: Thirty-Nine Steps|147114|The Thirty-Nine Steps (Richard Hannay, #1)|John Buchan|https://images.gr-assets.com/books/1388186765s/147114.jpg|2422487]. But this one is very solid and logical. Even when things go wrong, its never because of bad decisions, or at least not because of stupid decisions.

Its fast paced and short tale with very likable characters. There is one bit near the end where i felt it introduced too many new elements and we had a bit of an information dump but it did lead to some nice dramatic scenes.

Far better than the one biggles book i read as a kid :) . ( )
