A gripping story of treachery set in a scientific laboratory in post-war London Professor Sewell and his biological research team had spent years developing new methods of controlling epidemics. Now a smooth-talking government minister was refusing to let him publish important findings that could benefit the whole of mankind, in case a foreign power put them to more sinister use. Bob Marriott was bitterly disappointed. Hadn't everyone had a bellyful of distrust, destruction and death in the war that had just ended? Even his attractive colleague Lucy Byrne was one of its casualties, now dedicating her young life to looking after the crippled wreck of a man she had once hoped to marry. Fired by misguided loyalty and manipulated by false friends, Marriott decides to take matters into his own hands - with disastrous consequences.
