If they were following him, of course, they would use a different scrambler circuit than the one which was plugged into his own unit, but he would be able to hear the gabble of voices, even if he couldn't understand what they were saying.
So far, there hadn't been a sound; if he was being followed, his tailers weren't using the personal intercom units.
He didn't try to elude anyone who might be following. That, in itself, would be a giveaway. Let them watch, if they were watching. They wouldn't see anything but a man going to get himself a bit of dinner.
The Charles II Inn, on Regent Street, near Piccadilly Circus, was a haven of brightness in an otherwise Stygian London. It was one of those "old-fashioned" places—Restoration style of decoration, carried out in modern plastics. The oak panelling looked authentic enough, but it was just a little too glossy to be real.
Houston pushed open the door, stepped inside, removed his hat and coat and shook the dampness from them. As he handed them to the checker, he looked casually around. Dorrine was nowhere in sight, but he hadn't expected her to be. There would be no point in their meeting physically; it might even be downright dangerous.
The headwaiter, clad in the long waistcoat and full trunk-hose of the late Seventeenth Century, bowed punctiliously.
"You're alone, sir?"
"Alone, yes," Houston said. "I'll just be wanting a light supper and a drink or two."
"This way, sir."
Houston followed the man to a small table in the rear of the huge dining room. It was set for two, but the other place was quickly cleared away. Houston ordered an Irish-and-soda from a waiter who was only slightly less elaborately dressed than the headwaiter, and then settled himself down to wait. If he knew Dorrine, she would be on time to the minute.
