On the second floor of a characterless hotel in the British Crown Colony of Gibraltar, a lithe, agile man in his late fifties restlessly paced his bedroom.  His very British features, though pleasant an plainly honourable, indicated a choleric nature brought to the limit of its endurance.  A distraught lecturer, you might have thought, observing the bookish forward lean and loping stride of the errant forelock of the salt-and-pepper hair that repeatedly had to be disciplined with jerky back-handed shoves of a bony wrist.  Certainly it would not have occurred to many people, even in their most fanciful dreams, that he was a middle-ranking British civil servant, hauled from his desk in one of the more prosaic departments of Her Majesty's Foreign and Commonwealth Office to be dispatched on a top-secret mission of acute sensitivity.
