Rumpole defends a woman (Mrs Thripp) in a divorce action brought by her husband, claiming infidelity. She Who Must Be Obeyed (Mrs Rumpole) forms the opinion that her husband has a mistress - with curious results. Meanwhile, the aggrieved Thripp has begun a battle of notes.
Rumpole defends young Jim Timson, who has been grassed up for robbery with violence by 'Peanuts' Molloy - one of a rival gang of East End villains with whom the Timsons have an ancient feud. Unhappily, Jim's only alibi rests upon a junior member of the Molloy family. Meanwhile, Rumpole is having trouble communicating with his own son, Nick. He is also vexed by the question of who will be the new Head of Chambers at Number 3, Equity Court. Might he dare to dream that it could be him?
