Free The Last Oracle by James Rollins Page B

a few yards ahead. Gray trotted down the tunnel. He kept one arm up, his fingertips trailing along the run of pipes overhead. He took the first branch to get them out of direct view of the stairwell exit.
    A single low bark echoed to them.
    Gray urged their flight into a run.
    Elizabeth’s lab coat flapped behind her. Her flame burned through a nest of cobwebs as they raced around another turn.
    “Where are we going?” Kowalski asked.
    “Away,” Gray answered.
    “That’s your big plan? Away?”
    A burst of furious barking erupted. Shouts rang out. Their trail had been found.
    “Forget what I said,” Kowalski corrected. “ Away sounds just fine by me.”
    In a tight group, they fled into the maze of tunnels.
    Halfway across the city, Yuri sat on a bench under the spread of a cherry tree. It felt good to sit down. His knees ached, and his lower back threatened to spasm. He had dry-swallowed four tablets of Aleve. He had stronger medications back home, but nothing he dared bring into the States. It would be good to return to the Warren.
    He stretched a leg and rubbed a knee.
    As he rested, the sun was near to setting and cast long shadows across the parkland walkway. Steps away, a low cement wall bordered the path’s far side. Children and parents lined the edge and pointed down into the outdoor habitat beyond the wall. A small piece of China’s forestland hadbeen re-created: a rocky outcropping sectioned into grottoes, ponds, and misty streams. Shrubs decorated its steep slopes, along with weeping willows, cork trees, and several species of bamboo. The habitat’s two occupants, two Giant pandas on loan from China—Mei Xiang and Tian Tian—had captured the delighted attention of the zoo’s last few visitors.
    Including Sasha.
    The girl stood with her arms folded atop the lip of the stone wall. One shoe swung rhythmically to strike the cement. But it was slowing down.
    As he had hoped.
    Yuri had brought the girl to the National Zoological Park after her performance with Mapplethorpe. From long experience, he knew the calming effect animals had on his charges. Especially Sasha. Yuri had no need to test the BDNF levels in the girl’s spinal fluid. After such an intense episode, the hormone levels of “brain-derived neurotrophic factors” had surely spiked to dangerous levels. He had not been prepared. Caught off guard by her performance, he knew he had to calm her down quickly. Away from her home environment, she would be especially agitated, vulnerable. There was a risk of lasting neural damage. He had seen it before. It had taken them decades to discover the innate relationship between autistic children’s mental health and the palliative effect of their interaction with animals.
    So while Mapplethorpe executed a search of the natural history museum, Yuri had transported Sasha to the city’s famous zoological park. It was as close a facsimile to the Menagerie as he would find here in the foreign city.
    Sasha’s kicking slowed even further. She was ramping down. Still, the toe of her patent leather shoes had become badly scuffed. But better her shoes than her mind.
    Yuri felt a knot between his shoulder blades ease. He would get her on the next flight back to Russia. Once returned to the Warren, he would schedule her for a complete physical exam: blood chemistries, urinalysis, a full cranial CT scan. He had to be sure there was no damage.
    But more important, he needed an answer as to how she had induced an episode on her own. That shouldn’t have happened. The cortical implantmaintained a steady-state level of stimulation, tailored to each child’s ability. Sasha’s display back at Mapplethorpe’s office should not have happened unless her implant was remotely triggered to provoke such a response.
    So what had happened? Had there been a malfunction in her implant? Had someone else triggered it? Or even more disturbing, was Sasha growing beyond the yoke of their control?
    Despite the day’s heat and his
