This is the second story for boys (aged 9/10 upwards) dealing with the adventures of Jack Banks and his friends as featured in the first book, 'Jack Banks' Discovery'. Ideally the first story should be read before the second, but this is by no means essential to enjoyment of 'Jack Banks on Trial'. In this new story Jack aged 13, meets with a series of personal trials which put his new-found Christian faith very much under strain. He is greatly helped by his friends who include Ginger who befriended him in his early days at Harlington School, Themba the muscular son of a famous black American scientist, and Mickey the comically valiant smallest boy in the school. Mickey has an even more important and dangerous assignment than before in aiding Jack and his friends to combat the sinister plans of a mad doctor. The Jack Banks novels are set in the 1960's.
