Graham went inside, stopped at the hall porter’s desk for his key and to tell the night porter to call him at eight. Then, as the power for the lift was switched off at night, he climbed wearily up the stairs to his room on the second floor.

It was at the end of the corridor. He put the key in the lock, turned it, pushed the door open and, with his right hand, felt along the wall for the light switch.

The next moment there was a splinter of flame in the darkness and an ear-splitting detonation. A piece of plaster from the wall beside him stung his cheek. Before he could move or even think, the flame and the noise came again and it seemed as if a bar of white-hot metal had been suddenly pressed against the back of his hand. He cried out with pain and stumbled forward out of the light from the corridor into the darkness of the room. Another shot scattered plaster behind him.

There was silence. He was half leaning, half crouching against the wall by the bed, his ears singing from the din of the explosions. He was dimly aware that the window was open and that someone was moving by it. His hand seemed to be numb, but he could feel blood beginning to trickle between his fingers.

He remained motionless, his heart hammering at his head. The air reeked of cordite fumes. Then, as his eyes became used to the darkness, he saw that whoever had been at the window had left by it.

There would, he knew, be another light switch beside the bed. With his left hand he fumbled along the wall towards it. Then his hand touched the telephone. Hardly knowing what he was doing, he picked it up.

He heard a click as the night porter plugged in at the switchboard.

“Room thirty-six,” he said and was surprised to find that he was shouting. “Something has happened. I need help.”

He put the telephone down, blundered towards the bathroom and switched on the light there. The blood was pouring from a great gash across the back of his hand. Through the waves of nausea flowing from his stomach to his head, he could hear doors being flung open and excited voices in the corridor. Someone started hammering at the door.
