Darryl was a big man, well over six feet. His mother had been Chinese, Jesse had told me, and his father an African tribesman who had been getting an engineering degree at an American university when they met. Darryl’s features were an arresting blend of the two cultures. He looked like someone who should have been modeling or starring in movies, but he was a Ph.D. engineer working at the Pacific Northwest Laboratories in some sort of government hush-hush project.
