The hospital employed over two thousand nurses and hundreds of doctors, and the senior matron, Mima Puddicombe, was not old school, but ancient school. Florence Nightingale would happily have taken her to the Crimea. Emma enjoyed learning about the day-to-day problems Mima faced; at one end of the scale were grandiose consultants who imagined they were omnipotent, while at the other were patients who knew their rights. Somewhere in between were the nurses, who were expected to take care of both, while making sure a smile never left their faces. It was no wonder Mima had never married. She had two thousand anxious daughters, and a thousand unruly sons.

Emma had soon become engrossed in the daily routines of the hospital and was touched that Mima not only sought her advice, but treated her as an equal, sharing her anxieties and ambitions for the hospital to which she had devoted her life. But the meeting Emma was running late for had nothing to do with her duties at the hospital.

Earlier that morning, the prime minister had visited the Queen at Buckingham Palace and sought her permission to dissolve Parliament, so that a general election could be called. Emma had kept her promise to Margaret Thatcher and joined the election committee that oversaw the seventy-one constituencies in the West Country. She represented Bristol, with its seven seats, two of which were marginal, one of them her brother’s old stomping ground. For the next three weeks she and Giles would be standing on opposite sides of the road, imploring the electorate to support their cause.

Emma was thankful the campaign would be over in a month because she had to accept that Barrington’s and the hospital were not going to see a lot of her until after polling day. Harry never got used to her creeping into bed after midnight and then disappearing before he woke the following morning. Most men would have suspected their wife had a lover. Emma had three.

It was a bitterly cold afternoon and the two of them put on heavy coats, scarves and gloves before they went out for their usual walk. They only spoke of inconsequential matters until they reached the abandoned tin mine, where there would be no colonels, tourists or noisy children to disturb them.

“Do you have anything worthwhile to report, Comrade Brandt, or is this another wasted journey?”

“The Home Fleet will be carrying out exercises off Gibraltar on February twenty-seventh and twenty-eighth, when the Royal Navy’s new nuclear submarine will be in service for the first time.”

“How did you get hold of that piece of information?” said Pengelly.

“Barrington and I were invited to dine with the First Sea Lord at Admiralty House. I’ve found that if you remain silent long enough you blend into the background, like wallpaper.”

“Well done, comrade. I knew you’d come good in the end.”
