From London to Berlin involved a complete about face for barrister Martin Ainsworth when his government asked him to undertake a dangerous mission. Was the German girl he had once loved now a Communist agent? It was up to him not only to determine this--or so he was told--but to spot her contacts. He found his dual role disturbing emotionally, his lack of training a hazard unforeseen, and he proved to be more reckless than his peers had bargained for. Fast paced--unusual in approach--but a demanding plot for the reader as well as for the principals.
