A cold but bright weekend at Chequers opens with Winston Churchill in a bad temper. John Colville attributes part of Churchill’s irritability to too little sleep, and a trivial domestic grievance deepens it: Clementine Churchill has used his prized Australian honey to sweeten rhubarb. Into this mood comes Eric Duncannon, who arrives a day earlier than expected with his sister, Moyra Ponsonby. Because Eric seems ready to propose to Mary Churchill, his arrival immediately creates strain, since Mary is willing but her family largely disapproves and thinks she is too young.

That afternoon Churchill works in the garden but keeps returning to the recent destruction of Plymouth. Angry that German raids struck the city repeatedly with little interference, Churchill dictates a sharp note to Air Chief Marshal Charles Portal and John Moore-Brabazon demanding to know why the RAF has not fully equipped the squadron meant to deploy the Prof’s aerial mines and why those mines are not being used against German navigational beams. The effect is to show how strongly Churchill still backs the scheme, even though the mines remain unproven and most officials now place more hope in radar, beam-jamming, and decoy fires.

Churchill’s mood improves that night because fighting at Tobruk excites him and revives his appetite for dramatic war news. He stays up until three-thirty in the morning, joking, talking, and mixing business with conversation long after other guests give up and go to bed. Mary, however, retires already aware that the next day may change her life. In Berlin, meanwhile, Adolf Hitler and Joseph Goebbels amuse themselves by mocking a biography of Churchill that dwells on his eccentric habits, a reminder that Britain’s enemies still see him as both bizarre and dangerous.

Sunday at Chequers is colored by expectation that Eric will finally speak. New guests arrive, including Sarah Churchill, the Prof, Clarissa Spencer-Churchill, and Captain Alan Hillgarth, and the family’s reactions make the tension plain: Mary is anxious, Clementine dislikes the match, and others watch with curiosity or amusement. After lunch, instead of pursuing Mary directly, Eric goes off on a long walk with Clarissa, which Colville reads either as genuine distraction or a ploy to stir Mary’s jealousy. Eric then naps, seemingly to heighten the drama of his later appearance, while Churchill settles outside with top-secret papers and Iraq telegrams, working steadily and suspicious that Colville is trying to read his boxes.

At last Eric takes Mary into the White Parlor and proposes. Mary accepts, but only uncertainly; in her diary she records that she is in a daze and in a muddle, suggesting that the engagement is emotionally unresolved rather than triumphant. The chapter closes with Churchill once again working deep into the night in bed, attended by Colville and the Prof, while Colville leaves for London the next day exhausted. The weekend therefore ends with both public strain and private upheaval: Churchill remains locked in wartime pressure, and Mary’s future has shifted, though without real clarity or family harmony.
