Chen was about to overrule his junior colleague when their eyes met and he thought better of it. Li was clearly determined, and Chen had already overruled him once on the same subject. Perhaps the younger man should be allowed a little latitude to do things his way. He sighed. “Oh, well, I’ll tell the professor that other arrangements had already been made, and that while we are very grateful for the offer, Dr. Campbell’s services will not be required.” He paused and added, “But if this is something personal, Li Yan, then you are very foolish to allow it to cloud your professional judgment.”

He left, and Li stared into space, part of him wishing he had accepted the offer, part of him knowing that if he had, then the danger was that it would have become personal—in a way that might well have clouded his professional judgment. She had stirred in him feelings he had spent ten years suppressing, in favour of his career, and did not want to encourage now. He opened the file on The Needle to cast an eye over an old adversary.

The scrape of a door opening was sufficient to penetrate the fragile quality of her sleep. She blinked and lifted her head from a pillow that seemed uncommonly hard and unyielding. One arm had gone to sleep and would take longer to waken than she. Her neck seemed locked in one position. Through fuzzy, unfocused eyes, she saw a man approach the bed. What was a man doing in her bedroom? She raised herself up, blinking hard, heart pounding, and realised she wasn’t in bed. For a brief, panic-stricken moment she had not the faintest idea where she was, before suddenly the truth dawned on her. She had fallen asleep at her desk, head resting on her right forearm, in which her blood supply was now painfully re-establishing itself.

“You all right?” Bob asked.

“Yeah. Sorry. I guess I must have fallen asleep. Didn’t get much last night.”

Last night? When was that? Her brain couldn’t seem to find a context for anything. Like the blood finding its way back into the veins of her arm, memories of the last twenty-four hours leaked back into her consciousness accompanied by a series of pains—behind her eyes, at either temple, at the base of her neck. She remembered the autopsy, the lunch with Li, and her subsequent depression. And then she remembered being called in to see Professor Jiang and asked if she would be prepared to carry out another couple of autopsies and advise Deputy Section Chief Li’s murder inquiry in a consultative capacity.
