Outside, there were more alarms and two of the medical crew were still alive. Courault had succeeded in crawling a dozen metres down the corridor in a broad trail of her own blood, and one of her male colleagues, too weak to escape, was trying to prop himself up against the wall. The floor was slippery under him and he kept sliding back down. I ignored him and went after the woman. She stopped when she heard my footsteps, twisted her head to look round and then began to crawl again, frantically. I stamped a foot down between her shoulders to make her stop and then kicked her onto her back.
