PROLOGUE

      May 3rd, 1958.

      If you could call a ten by six wooden box mounted on a four-wheel trailer an office, then I was sitting in my office. I’d been sitting there for four hours, the earphones were beginning to hurt and the darkness was coming in from the swamps and the sea. But if I had to sit there all night, then I was going to do just that: those earphones were the most important thing in the world. They were the only remaining contact between me and all the world held for me.

      Peter should have been within radio range three hours ago. It was a long haul north from Barranquilla, but we’d made that haul a score of times before. Our three DCs were old but as mechanically perfect as unceasing care and meticulous attention could make them. Pete was a fine pilot, Barry a crack navigator, the West Caribbean forecast had been good and it was far too early in the season for hurricanes.

      There was no conceivable reason why they shouldn’t have been on the air hours ago. As it was, they must have already passed the point of nearest approach and be drawing away to the north, towards Tampa, their destination. Could they have disobeyed my instructions to make the long dog-leg by the Yucatan Strait and flown the direct route over Cuba instead? All sorts of unpleasant things could happen to planes flying over war-torn Cuba those days. It seemed unlikely, and when I thought of the cargo they were carrying it seemed impossible. Where any element of risk was concerned, Pete was even more cautious and far-seeing than myself.

      Over in the corner of my office on wheels a radio was playing softly. It was tuned in to some English-speaking station and for the second time that evening some hill-billy guitar-player was singing softly of the death of mother or wife or sweetheart, I wasn’t sure which. ‘My Red Rose Has Turned to White’ it was called. Red for life and white for death. Red and white – the colours of the three planes of our Trans-Carib Air Charter service. I was glad when the song stopped.

      There was nothing much else in the office. A desk, two chairs, a filing cabinet and the big RCA receiver-transmitter powered by a heavy TRS cable that ran through the hole in the door and snaked across the grass and mud and one corner of the tarmac to the main terminal buildings. And there was a mirror. Elizabeth had put that up the only time she’d ever been here and I’d never got around to taking it down.

      I looked in the mirror and that was a mistake. Black hair, black brows, dark blue eyes and a white strained haggard face to remind me how desperately worried I was. As if I needed reminding. I looked away and stared out of the window.

      That was hardly any better. The only advantage was that I could no longer see myself. I certainly couldn’t see anything else. Even at the best of times there was little enough to see through that window, just the ten empty desolate miles of flat swampland stretching from the
