Clifton is put in charge of training a young MI5 prodigy. Holidaying in the country, Clifton receives the unexpected – and unwelcome – visit of a MI5 bigwig. He finds himself reinstated against his will, and tasked with finalising the training of a promising new recruit of the Intelligence Service: Sir Jason. The young man is sharp, well- educated, knows both techniques and theory like the back of his hand... The problem, as Clifton soon discovers, is that when the time for action comes, he is inevitably paralysed by fear!
