In the second week of April, Taggie Campbell-Black crossed the world and fell head over heels in love for the second time in her life. The flight to Bogotá, delayed by engine trouble at Caracas, took fifteen hours. Taggie, who’d hardly eaten or slept since Rupert broke the news of their journey, could only manage half a glass of champagne. Nor, being very dyslexic, was she able to lose herself in Danielle Steel or Catherine Cookson, nor even concentrate on Robbie Coltrane camping it up as a nun on the in-flight movie. She could only clutch Rupert’s hand, praying over and over again: Please God let it happen.

By contrast Rupert, concealing equal nerves behind his habitual deadpan langour, had drunk far too much as he sat thumbing through a glossary at the back of a Bogotá guide book.

‘I now know the Colombian for stupid bugger, prick, jerk, double bed, air-conditioning, rum and cocaine, so we should be OK.’

At El Dorado Airport, the policemen fingered their guns. Seeing an affluent-looking gringo, the taxi-driver turned off his meter. As they drove past interminable whore-houses and dives blaring forth music, past skyscrapers next to crumbling shacks, Rupert’s hangover was assaulted as much by the shroud of black diesel fumes that blanketed the city as by the furiously honking almost static rush-hour traffic. There was rubbish everywhere. On every pavement, pimps with dead eyes, drug pushers carrying suitcases bulging with notes, tarts in tight dresses pushed aside beggars on crutches and stepped over grubby sloe-eyed children playing in the gutter. How could anything good come out of such a hell-hole?
