‘Might take a while,’ Hart said. ‘You know, getting hold of that kind of information. The students who did the research might remember, but I’m guessing their notes were probably among the casualties of that burglary last night.’
‘Let’s have a look at some of the pics,’ Li said, and he leaned in as Hart double-clicked on one of the Pics folders
Its window opened up and Hart cursed. ‘Shit!’ The folder was empty. He went systematically through the other five. Empty. ‘What the hell …’
Lyang said, ‘Why would she upload six empty folders?’
‘Christ knows,’ Hart said. ‘She was probably in a hurry. Maybe the MERMER software puts the pics somewhere else when it’s running a demo and she never retrieved them. I just don’t know.’
‘Maybe you’d better check the Graphs folders,’ Margaret suggested.
Hart opened up Graphs A. Its window contained three files, small icons representing single sheets of paper with folded corners. There was a design within each icon which seemed to be made up from the letters MRM, and each file was labelled with a title in a coloured strip beneath it. Graph 1, Graph 2, Graph 3. ‘She must have done three run-throughs,’ Hart said.
‘She did,’ Li confirmed. ‘Can you open those up?’
Hart shook his head. ‘I don’t have the MERMER software.’ And to prove his point he double-clicked on a file icon and a message in a box appeared mid-screen. File cannot be opened because the application software that created it cannot be found.
‘So what use is any of this stuff?’ Lyang said. ‘We don’t have any of the pics. We don’t know which graph relates to who …’
And Margaret added. ‘We don’t know how any of it relates to her murder, or even if it does.’
Li was staring grimly at the screen. His disappointment was nearly choking him. ‘Open up each of the folders,’ he said.
Hart shrugged. ‘What’s the point? We can’t open up any of the files.’
‘Humour me.’
Hart started going through each of the folders as Li had asked. They were all the same. Until he got to Graphs D, and his hand froze on the mouse. For instead of the files being labelled, Graph 1, Graph 2, Graph 3. They were labelled, LIAR, LIAR, LIAR.
Wednesday
Chapter Nine
I
It was dark when Li left his apartment. Margaret was still asleep, her first undisturbed night for months. The apartment had seemed strangely empty when they got in the night before, with Li Jon spending the night at Mei Yuan’s. It was odd how a presence you took for granted was never more apparent than when it was no longer there. Margaret had fallen asleep almost immediately. Li had drifted once or twice, but for most of the long hours of the night had lain awake staring at the ceiling in the reflected light from the streetlamps outside. He knew he was in trouble, and had been playing a mind game his uncle had taught him. Take sequential facts that led to a conclusion and rearrange them in any order. Then look at them again with a fresh eye. It was amazing just how often you could reach a different conclusion. But no matter how many times Li rearranged the events of the last forty-eight hours, the conclusion always remained the same. And it scared him.
As he drove west on Changan, retracing his journey of the previous night, the first splinters of sunlight shot like arrows down the length of the city’s east-west artery, blinding him when he glanced in the rear-view mirror. It heralded the break of a day that filled him with dread. It brought no illumination. Merely contrast with the darkness he carried in his heart.
He turned north again at the Muxidi intersection and drove past the academy on his right, and Yuyuantan Park on his left. There was little traffic on the road yet, but even as he looked, the cycle lanes were filling up with huddled figures braving the subzero temperature to cross this city of thirteen million inhabitants to factories and offices on its far-flung outskirts. When he reached the traffic lights at the Yuetan Footbridge, he turned right into Yuetan Nan Jie, and there ahead of him were the rows of pink and white four-storey apartment blocks that housed the most senior police officers in China.
He showed his ID to the guard on duty at the gate and drove into the forecourt parking lot of the first block. He got out of the car and stretched stiff and tired limbs, breathing in the cold, harsh air, and trying to blink away the grit in his eyes. He pulled his long, black coat tightly around himself and looked up at the picture windows with their views of the parkland below, the open balconies where the privileged could dine in the shady cool of a summer’s evening, and knew he would never reach those dizzy heights. Not that he wasn’t good enough. He was a better cop than most of the residents of these luxury apartments. But he had a big mouth, which he was about to open again. And this time, even he was frightened of the consequences.
Commissioner Zhu was still in his dressing gown — black silk embroidered with red and gold dragons — when he opened his door to Li. He had been unable to disguise his surprise when Li announced himself on the intercom. A moment’s silence, then a curt, ‘You’d better come up.’
He ushered Li into the spacious living room at the front of the apartment. Net curtains as fine as gossamer hung over sliding glass doors that led out on to the balcony. In the distance, above the tops of the autumn trees, you could just see the roof of the Chinese Academy of Sciences. Li could hear the Commissioner’s wife in the kitchen, where she had clearly been sent and told to stay. The Commissioner stood with his back to the glass doors, his legs apart, arms folded. Against the light Li could not see his face, only the reflected light from his rimless glasses. Beyond him the sky was a deep orange. ‘This had better be good, Li. I’m not accustomed to being dragged from my bed by junior officers.’
Li took a deep breath. ‘I believe that one of the six of us who took the MERMER test on Monday afternoon murdered Lynn Pan,’ he said.
Zhu remained motionless, and Li could not see in his face what impact his statement had made. The Commissioner said nothing for what seemed like a very long time. Eventually he cleared his throat and said in a quiet voice, ‘Which one of us?’
‘I don’t know.’
‘Then what makes you think it was any of us?’
And Li told him. About the DNA mismatch, about how only someone with inside knowledge of the police investigation could have so accurately mimicked the Beijing Ripper. About the caller pretending to be him, luring Pan to a rendezvous with death at the Millennium Monument. About Pan’s fears, expressed in her e-mail to Hart, and her private folders on the academy website, with the three graphs marked, Liar, Liar, Liar.
‘But you don’t know whose graphs they were?’
‘No, Commissioner.’
‘And how do you propose to find out?’
‘I’ve asked Bill Hart to gather together all the various pieces of information necessary to make that apparent. Miss Pan’s assistant, and the students who took part in the demonstration should be able to provide most of what he needs.’
For the first time, the Commissioner unfolded his arms and leaned forward to take a cigarette from a wooden box on a lacquered table. He lit it and blew smoke towards the ceiling. It hung in the still air of the apartment, backlit by the dawn.
‘And supposing you do identify this liar. What then? How does that in any way prove that he murdered Lynn Pan?’
‘It doesn’t. But it would tell us where to look.’
‘And his motive?’
‘The lie, presumably.’
The Commissioner snorted his derision. ‘What sort of a lie told during an innocent demonstration could possibly motivate murder? And anyway, how could he lie? We weren’t asked any questions.’
