‘What about the complete mapping of the poultry genome?’ asked the black scientist, displaying his medical-publication awareness.
Once more, fleetingly, Parnell had the impression of being tested. ‘It gives us – and every other researcher and group trying to do what we’re attempting – three thousand million bases, to compare against three thousand million human genetic bases, to find one, just one, that might provide a mutating-inviting host cell.’
‘Which you’re doing?’
‘Of course we’re doing it,’ said Parnell, although refusing to rise to the other man’s challenge. ‘But there are at least six different strains of domestic chicken farmed in China, quite apart from all the other global test species. But let’s just stay with China. Which, alone, gives us a multiplication of eighteen thousand million.’
‘I can work out the mathematics for myself,’ patronized Benn.
‘But not, chemically, a quicker way towards a treatment!’
‘Maybe neither of us will be the lucky ones,’ Benn said, with forced philosophy.
‘I didn’t believe we were allowed to think like that here at Dubette.’
‘We’re not,’ smiled the other man. ‘Don’t tell anyone I ever said it.’
‘I spoke with Dwight yesterday, about the work you both did on the French stuff,’ announced Parnell, impatient with the sparring.
‘It was just placebo additions to existing formulae,’ dismissed Benn, the confidence confirming Parnell’s belief of prior consultation with Dwight Newton.
‘Dwight explained. He agreed the improvements should be added to everything else I’ve been given, to be looked at genetically some time.’
‘Not sure we’ve got any batch samples left,’ said Benn. ‘Once we established the safety, I think they were all destroyed.’
‘Could you check?’
‘Sure.’
‘And if you don’t have made-up samples, you’d have the old and new formulae? And I could get shipped from Paris the old against the new, couldn’t I?’ insisted Parnell.
‘Sure,’ said Benn again. ‘Like I said, I’ll check.’
By noon the following day, Parnell received fifteen differently name-marked phials, with the comparable number of Dubette commercially packaged and identified bottles previously produced in France. Using that comparison he quickly discovered the major differences between the old and new formulae were liulousine and beneuflous, which the pharmacological register described as expectorants, and a flavouring agent called rifofludine, which in hot climates had a limited function as a preservative when refrigeration was unavailable. There were also six colouring agents, all of which were listed as simply that, non-medically-active colourants.
Also that day, the raw research material, each with its research notes, arrived from San Diego and London, both far more extensive and detailed than Parnell had anticipated. Parnell stored everything from Russell Benn’s division under refrigeration, separating the rifofludine for later temperature match. The whole operation took him less than an hour and was completed long before Russell Benn unexpectedly came into the pharmacogenomics unit.
‘Get everything you wanted?’ greeted the man.
‘If fifteen samples are everything I wanted, then yes, I have. Thanks.’ Parnell saw Benn looking at the just-opened packages occupying virtually all of his desk. ‘And it took all of this to discover the haemagglutinin protein of the 1918 flu epidemic.’
‘What are you going to do with it?’
‘Study it. Hope to get an idea – a possible path to follow at least. Somewhere among all this is the specific attempt by the Scripps Institute and the London School of Medicine to match the chicken genome. If they’d done it already, it would have been announced. I’m hoping we’ll get a lead from everything they’ve done, from which we might find a different approach for our particular needs.’
‘And if you don’t?’
‘We go on stumbling about in the dark.’
‘You get a lead I could follow as well, I’d appreciate your telling me…’
‘If I get any sort of direction, I’m not going to keep it to myself,’ assured Parnell.
There was an overwhelming temptation to start on the material at once, but Parnell remained strictly professional, actually helping Kathy Richardson make duplicates not just for the four seconded to the specific influenza team, but for Mark Easton and Peter Battey as well. He included the two men in the regular end-of-day general discussion, offering each their full dossier cases and suggesting their spare-time input.
‘What spare time?’ mocked the pebble-spectacled Battey.
‘Coffee breaks, lunch periods, those sort of times,’ Parnell partially mocked back. ‘I don’t know if we’re ever going to get anywhere, but if we don’t it won’t be for want of trying.’
‘I’d certainly like to get out of the cul-de-sac I’m in at the moment,’ complained Sato, whose Internet find the 1918 genetic discoveries had been. ‘All I’m doing is killing mice.’
‘What are you cutting your genetic strings down to, for ease of working?’ asked Lapidus.
‘Ten thousand at a time,’ said Sato. ‘You?’
‘Five.’
‘This way we’ll still be comparing when we’re old and grey,’ said Beverley Jackson.
‘Maybe we take a break from routine practical application and instead go through this stuff looking for a new approach,’ proposed Parnell. ‘The source notes alone might lead us somewhere. One, or both, will have already covered a lot of the ground that we’re duplicating.’
‘Is that an order?’ asked Beverley.
‘Let’s give it a shot, stop our eyes glazing over,’ said Parnell.
They all worked on late that night, with Parnell the last to leave, taking more files with him to continue working on at home. It had become a no-longer-unsettling habit to check his surroundings crossing the now sparsely occupied car park and constantly to check his mirrors once he began moving. He drove with his mind hedge-hopping between what he’d been studying – none of which had given him any new ideas – and stray, unconnected thoughts. Enquiring when he could have his own car back would give him an excuse to speak to the FBI agents in the hope of learning of any progress. There hadn’t been any mention of the second autopsy at their last meeting, but the funeral wouldn’t have been allowed unless it had been completed. He had no doubt that Russell Benn had been forewarned of his approach about France, which made nonsense of the man’s prevarication about there not being any surviving samples when there blatantly had been. How – why – had Rebecca had the Air France flight number? It had to be significant. But how? Why hadn’t she done as she’d promised and stopped probing? Had those headlights now in his rear-view mirror been there as long as he imagined? He slowed, eyes constantly flickering to the mirror, the more so when the lights grew bigger, brighter, but abruptly the following car pulled out and past with an impatient blast on the horn. No hurry to get home. No one waiting for him. He supposed he should eat, although he wasn’t hungry. He couldn’t remember what prepacked meals he had in the refrigerator. He’d choose something he could cut one-handed, with just a fork, so he could eat and read at the same time. He was still less than halfway through the San Diego material. He had to avoid the growing temptation to go out of sequence and read all the source notes instead of waiting for their numbered listing in the developing research narrative. Had Dwight Newton and Russell Benn told him the truth? He’d look further than the pharmacological register to find out more about liulousine, beneuflous and rifofludine. And the supposed harmless flavourings. But carefully. Unsuspected – unseen – by anyone. Rebecca’s murder was unquestionably connected to Dubette. And despite every FBI and lawyer’s warning, Parnell remained determined to discover that connection. Until he did, he was going to have his eyes a lot on the rear-view mirror, watching for headlights closing behind.
