“I’m sorry — I shouldn’t have said that.” Nunn sounded irritated rather than apologetic.

Colebrook, ever watchful, gripped Hasson’s arm just above the elbow and squeezed it firmly. “Take two capsules right now, Rob. That’s an order.”

Embarrassed and shamed, Hasson brought the plastic dispenser out of his pocket, fed two green-and-gold capsules into his palm and swallowed them. They felt dry and weightless in his mouth, like the blown-out eggs of tiny birds.

Nun cleared his throat. “The point I was making is that the Sullivan case is out of the hands of the Air Police and we have to do what SCQ tells us. If they think your evidence is worth the Sullivan organisation’s trying to shut you up for good we have to accept what they say. It’s their patch.”

“I know, but it’s all so …” Hasson gazed around him helplessly. “I mean … fake identity, fake passport! How am I going to get used to calling myself Haldane?”

“That doesn’t seem much of a problem to me,” Nunn said brusquely, compressing his lips. “Try to adopt a more positive attitude, Rob. Get yourself off to Canada and do a lot of sleeping and eating and drinking, and enjoy it while you have the chance. We’ll send for you when you have to testify.”

“Speaking as a medical man, that sounds like good advice.” Colebrook opened the door at his side, got out and went to the back of the car. He lifted the lid of the trunk and began unloading Hasson’s cases.

“I won’t get out,” Nunn said, reaching a hand into the rear seat. “Take care of yourself, Rob.”

“Thanks.” Hasson shook the offered hand and let himself out of the car. The sky had completely cleared now, to the palest wash of blue, and a searching breeze was whipping in from the Atlantic. Hasson shivered as he thought of the thousands of kilometres of open sea that lay between him and his destination. The journey seemed too great for any aircraft, and even more incredible was the idea that only a few months ago he, Robert Hasson, faced with the task of getting to Canada, would have brashly strapped on a counter-gravity harness and made the flight alone, with no protection other than a helmet and heated suit.
