It was Clancy who put in, “So why does a guy like that take a job as a security guard, Mr. President – and on a forged green card?”

“Something else Roper discovered.”

“Everything about us is on some sort of record these days,” the President said. “So General Ferguson tipped you off.”

“No, there was more to it than that. Ferguson found Roper’s discovery interesting enough to check it out a little on his side. He sent his assistant, Detective Superintendent Hannah Bernstein of Special Branch at Scotland Yard, to visit Morgan’s home address in London. She discovered that the mother was in a wheelchair after a bad automobile accident that had killed the father five years ago. Bernstein posed as a welfare officer to gain her confidence. Discovered many interesting things.”

“Such as?”

“The mother had been disowned by her family for marrying out of the Muslim faith. Her son had been raised a Christian. After the accident, however, she rediscovered her faith and her son would take her to the local mosque, where she was received well. And the truly interesting thing was that she said her son had discovered Islam himself, and embraced it.”

Cazalet was looking grim. “So it all begins to fit.”

“Especially when she said he’d gone to New York on vacation.”

“Has Ferguson taken it any further?”

“No, he’s waiting to hear from us.”

Cazalet nodded. “So Morgan obviously arrived on somebody’s orders.”

“Exactly. An organization in the UK with some sort of contacts in New York.”

“Why didn’t you arrest him the minute you got the story from London?”

“I wanted to see where it would lead, and Charles Ferguson agreed. It was highly unlikely he was just a deranged loner, so there was a chance he could lead us to his New York contacts.”

“Only he didn’t.”

“The few days he was here, he didn’t meet a soul. I had two old FBI hands follow him when we found that the address he’d given Icon Security was false. He was staying in a small hotel; they discreetly gained access to his room and found nothing. No ID on him, no passport at his death. I’d say they’d all been destroyed, probably on orders from his handlers in London.”
