By the year 1949, life in Walworth has almost returned to normal. Sammy and Boots, now in a highly successful partnership, are rebuilding the old family firm. But an old enemy resurfaces - Mr Ben Ford, better known as the Fat Man, who seems determined to ruin the various branches of this growing business. It takes all the well-known Adams ingenuity and determination to outwit the thugs in the Fat Man's pay.
Meanwhile, an attractive blonde woman shopping in the market has caught Boots's eye. But Polly does not need to feel apprehensive - the sight of this woman has stirred the worst of memories for Boots, from the darkest days of the war. And on a happier note, there is some surprising news for Chinese Lady - news which will affect the whole of the Adams family.
