Hot water and cold juice. The after-run shower was a daily reward for one of his few healthy habits. He worked too hard, ate in the irregular way of bachelors, slept too little, and certainly drank more than the five units of alcohol a week decreed, with sanctimonious relish, by the company doctor. But he ran, and he was young. Forty was several years away, and by then, he told himself, he would have his life and his finances in order, ready to settle down and-who knows-make another gallant attempt at matrimony.

He studied his reflection in the shaving mirror. Blue eyes, only slightly bloodshot; dark brown hair, cut short in the current fashion; skin taut over high cheekbones. As yet, no obvious bags or wrinkles. Could be worse, he thought, as he stepped over the wet towel and discarded running clothes on the bathroom floor.

Five minutes later, he was ready to conquer the financial universe, dressed in the uniform and trappings of the modern young executive: dark suit, dark blue shirt, dark tie, a bulky watch designed for deep-sea divers obsessed with punctuality, cell phone and car keys at the ready. He ducked through the drizzle and into the obligatory black BMW for the drive to the City, where today, he felt sure, the long-awaited deal would come through. And then the bonus. He’d finish furnishing the apartment, hire a housecleaner to keep it spotless, take a few days off, and drive down to Saint-Tropez before all the girls went back to Paris. Not even the weather forecast on the radio-scattered showers, followed by outbreaks of heavier rain, with a chance of hail-could dampen his spirits. This was going to be a good day.

At this time of the morning, twenty minutes should have been more than enough to get him into the Lawton Brothers’ offices. They were at the top end of Threadneedle Street -“handy for the Bank of England,” as the senior Lawton brother was fond of telling his prospective clients.
