“What?” he said, confused.

“Rescue Service helicopter coming in. Two patients. An injured man and a younger woman. The woman has a gunshot wound.”

“Alright,” Jonasson said wearily.

He felt groggy although he had slept for only half an hour. He was on the night shift in A. amp; E. at Sahlgrenska hospital in Göteborg. It had been a strenuous evening. Since he had come on duty at 6.00 p.m., the hospital had received four victims of a head-on collision outside Lindome. One was pronounced D.O.A. He had treated a waitress whose legs had been scalded in an accident at a restaurant on Avenyn, and he had saved the life of a four-year-old boy who arrived at the hospital with respiratory failure after swallowing the wheel of a toy car. He had patched up a girl who had ridden her bike into a ditch that the road-repair department had chosen to dig close to the end of a bike path; the warning barriers had been tipped into the hole. She had fourteen stitches in her face and would need two new front teeth. Jonasson had also sewn part of a thumb back on to an enthusiastic carpenter who had managed to slice it off.

By 12.30 the steady flow of emergency cases had eased off. He had made a round to check on the state of his patients, and then gone back to the staff bedroom to try to rest for a while. He was on duty until 6.00 in the morning, and seldom got the chance to sleep even if no emergency patients came in. But this time he had fallen asleep almost as soon as he turned out the light.

Nurse Nicander handed him a cup of tea. She had not been given any details about the incoming cases.

Jonasson saw lightning out over the sea. He knew that the helicopter was coming in in the nick of time. All of a sudden a heavy downpour lashed at the window. The storm had moved in over Göteborg.

He heard the sound of the chopper and watched as it banked through the storm squalls down towards the helipad. For a second he held his breath when the pilot seemed to have difficulty controlling the aircraft. Then it vanished from his field of view and he heard the engine slowing to land. He took a hasty swallow of his tea and set down the cup.
