They were last off the aircraft.

The middle-aged man and the boy in his early twenties had not joined the queue of passengers who scrambled along the aisle towards the forward exit. The pilot shut down his engines and the music cascaded from the hidden loud- speakers in the ceiling. The man ignored the buffeting his elbow took on the arm rest of his seat as passengers' bags and belongings and Duty Free parcels pummelled against him. He was engrossed in his book, dog-eared and much consulted, a tome on European birds: his attention was held by the winter markings and juvenile colourings of the Golden, Grey, Ringed and Kentish plovers.

There was nothing he could learn from text or illustrations, but he handled the pages as a widow will consult a much used family Bible.

When he was jolted by a bulging plastic carrier boasting the name of a fur shop on the Rue du Mont Blanc, he looked up, just the once, in irritation. But it was momentary and replaced by the satisfaction of knowing that Heathrow's Customs and Excise staff reserved their closest scrutiny for travellers from Geneva.

They made strange and unlikely companions. The man was round-faced, bald-headed with untidy strands of wispy grey hair settling about his ears. The boy was striking in a muscular, lissom, empty fashion, good looking in an inadequate way, with weather in his cheeks.

The man wore a tired suit with a small tidy darn on the right elbow and his shoes were brilliandy polished. The boy was dressed in sports coat and slacks that made only a casual fit, too long at the sleeves, too short at the legs, a temporary and borrowed habit.

The boy shivered as he waited for the aisle to clear. It was more than five hours since he had been in the water, but the cold still nestled close to his bones and the chill had settled on his skin beneath the singlet and underpants and socks that had been given to him.
