Monkey On His Back

Under the cloud of cast-off identities lay the shape of another man— was it himself?
HE was walking endlessly down a long, glass-walled corridor. Bright sunlight slanted in through one wall, on the blue knapsack across his shoulders. Who he was, and what he was doing here, was clouded. The truth lurked in some corner of his consciousness, but it was not reached by surface awareness.
The corridor opened at last into a large high-domed room, much like a railway station or an air terminal. He walked straight ahead.
At the sight of him a man leaning negligently against a stone pillar, to his right but within vision, straightened and barked an order to him, “Halt!” He lengthened his stride but gave no other sign.
Shouts and the sound of charging feet came from behind him. He cut to the right, running toward the escalator to the second floor. Another pair of men were hurrying down, two steps at a stride. With no break in pace he veered into an opening beside the escalator.
At the first turn he saw that the aisle merely circled the stairway, coming out into the depot again on the other side. It was a trap. He glanced quickly around him.
At the rear of the space was a row of lockers for traveler use. He slipped a coin into a pay slot, opened the zipper on his bag and pulled out a flat briefcase. It took him only a few seconds to push the case into the compartment, lock it and slide the key along the floor beneath the locker.
There was nothing to do after that—except wait.
The men pursuing him came hurtling around the turn in the aisle. He kicked his knapsack to one side, spreading his feet wide with an instinctive motion.
Until that instant he had intended to fight. Now he swiftly reassessed the odds. There were five of them, he saw. He should be able to incapacitate two or three and break out. But the fact that they had been expecting him meant that others would very probably be waiting outside. His best course now was to sham ignorance. He relaxed.
