This is a gripping and intelligently written first novel. Ferris mixes a pacey intertwined plot with great characterisation and evocative descriptions of the grey, uncertain, haphazard London immediately after World War II. He changes pace very well, and applies some very sharp dialogue in his character development. The baddies are pretty bad, the goodies suffer a lot of fear, doubt and uncertainty before their goodness starts to shine through. Altogether, a very potent and addictive cocktail - I can't wait for the next one!
