Inspector Lynley 18 - Just One Evil Act

whoever it was she had left me for. To him or to someone else.”
    “Do you mean that the first time she left you, she might have left you for someone other than Signor Mura?”
    “That is what I mean,” Azhar affirmed. “We did not discuss it. When we saw each other again once Hadiyyah had been taken, there was no point to that sort of discussion.”
    “And once you reached Italy?”
    Azhar drew his eyebrows together as if to say, What about it? He didn’t answer at first as Signora Vallera came into the room with the
caffè
and a plate of
biscotti
. They were shaped like balls and covered with powdered sugar. Salvatore took one and let it melt in his mouth. Signora Vallera poured
caffè
from a tall crockery jug.
    When she’d departed, Azhar said, “
Non capisco, Ispettore
,” and waited for elucidation.
    Salvatore said, “I wonder if you carried with you the understandable anger at this woman for her sins against you.”
    “We all commit sins against each other,” Azhar said. “I have no immunity from this. But I think she and I had forgiven each other. Hadiyyah was—she is—more important than the grievances Angelina and I had.”
    “So you did hold grievances.” And when Azhar nodded, “Yet in your time here, those did not rise between you? You did not accuse? There were no recriminations?”
    Birgit stumbled a bit with the word
recriminations
. But after a pause to consult a pocket dictionary, she carried on. Azhar said that there had been no recriminations once Angelina understood that he had had nothing to do with their daughter’s disappearance, although it had taken him much to convince her of this, including a call upon his estranged wife and their children as well as proof of his own presence in Berlin at the time of Hadiyyah’s disappearance.
    “Ah, yes, Berlin,” Salvatore said. “A conference,
vero
?”
    Azhar nodded. A conference of microbiologists, he said.
    “Many of them?”
    Perhaps three hundred, Azhar told him.
    “Tell me, what does a microbiologist do? Forgive my ignorance. We policemen . . . ?” Salvatore smiled regretfully. “Our lives, they are very narrow, you see.” He put a packet of sugar into his
caffè
. He took another
biscotto
and let it melt on his tongue like the other.
    Azhar explained, although he didn’t look convinced by Salvatore’s declaration of ignorance. He spoke about the classes he taught, the graduate and postgraduate students he worked with, the studies carried out in his laboratory, and the papers he wrote as a result of those studies. He spoke of conferences and colleagues as well.
    “Dangerous things, these microbes, I would think,” Salvatore said.
    Azhar explained that microbes came in all shapes and sizes and levels of danger. Some, he said, were completely benign.
    “But one does not interest oneself with those that are benign?” Salvatore said.
    “I do not.”
    “Yet to protect yourself from the danger of exposure to them? This must be crucial, eh?”
    “When one works with dangerous microbes, there are many safeguards,” Azhar informed him. “And laboratories are differently designated according to what’s studied within them. Those that have higher biohazard levels have more safeguards built into them.”
    “
Sì,
sì, capisco
. But let me ask: What, really, is the point of studying such dangerous little things as these microbes?”
    “To understand how they mutate,” Azhar said, “to develop a treatment should one be infected by them, to increase the response time when one is trying to locate the source. There are many reasons to study these microbes.”
    “Just as there are many types of microbes, eh?”
    “Many types of microbes,” he agreed. “As vast as the universe and mutating all the time.”
    Salvatore nodded thoughtfully. He poured more
caffè
into his cup from the crockery jug and held it up to both Birgit and Azhar. Birgit nodded; Azhar shook his head. He tapped his fingers against the tabletop and looked beyond Salvatore towards the door of the room. Hadiyyah’s high, excited chattering came to them. She was speaking Italian. Children, he thought, were so quick to pick up languages.
    “And in your laboratory,
Dottore
? What is being studied there? And is this laboratory a . . . what did you call it? A biohazard laboratory?”
    “We study the evolutionary genetics of infectious diseases,” he said.
    “
Molto complesso
,” Salvatore murmured.
    This required no translation. “It is complex
