The Fallen Angel

closing the cabinet. “We shared everything—our mother’s womb, our nursery, our clothing. You might find this rather strange, Mr. Allon, but I always assumed my sister and I would share the same coffin.”
    She walked over to the refrigerator. On the door, held in place by a magnet, was a photograph of the sisters posed along the railing of a ferry. Even Gabriel, who had an artist’s appreciation of the human form, could scarcely tell one from the other.
    “It was taken during a day cruise on Lake Como last August,” said Paola Andreatti. “I was recently separated from my husband. Claudia and I went alone, just the two of us. I paid, of course. Employees of the Vatican can’t afford to stay in five-star hotels. It was the best vacation I’d had in years. Claudia said all the appropriate things about my pending divorce, but I suspect she was secretly relieved. It meant she would have me to herself again.”
    She opened the refrigerator, exhaled heavily, and began placing the contents in a plastic rubbish bin. “As of this moment,” she said, “several hundred million people around the world believe my sister committed suicide. But not one of them knows that Gabriel Allon, a former Israeli intelligence agent and friend of the Vatican, is now sitting at her kitchen table.”
    “I’d prefer to keep it that way.”
    “I’m sure the men of the Vatican would, too. Because your presence suggests they believe there’s more to my sister’s death than merely a soul in distress.”
    Gabriel made no response.
    “Do you believe Claudia killed herself?”
    “No,” Gabriel said. “I do not believe Claudia killed herself.”
    “Why not?”
    He told her about the broken necklace, about the shoes, and about the perfect rectangle on her sister’s desk where no dust was present. “You weren’t the first person to come here tonight,” he said. “Others came before you. They were professionals. They took anything that might be incriminating, including your sister’s laptop computer.”
    She closed the refrigerator and stared silently at the photograph on the door.
    “You did notice the computer was missing, didn’t you?”
    “It’s not the only thing,” she said softly.
    “What else?”
    “My sister never went to sleep at night without writing a few lines in her diary. She kept it on her bedside table. It’s no longer there.” Paola Andreatti looked at Gabriel for a moment without speaking. “How long will it be necessary to allow this terrible lie about my sister to persist?”
    “For as long as it takes to discover the truth. But I can’t do it alone. I’m going to need your help.”
    “What kind of help?”
    “You can start by telling me about your sister.”
    “And then?”
    “We’re going to search this apartment together one more time.”
    “I thought you said the men were professionals.”
    “They were,” said Gabriel. “But sometimes even professionals make mistakes.”
     
     
    They moved into the sitting room and settled amid Claudia’s books and papers. Paola Andreatti spoke of her sister as though she were speaking of herself. For Gabriel, it was like interviewing a corpse that had been granted the ability to speak.
    “Did she use any other e-mail address besides her Vatican account?”
    “Everyone at the Vatican keeps a private account. Especially the priests.”
    She recited a Gmail address. Gabriel didn’t need to write it down; his uncanny ability to mimic the brushstrokes of the Old Masters was matched only by the precision of his memory. Besides, he thought, when one is pitted against professionals, it is best to behave like one.
    The interview complete, they searched the apartment. Chiara and Paola Andreatti saw to the bedroom while Gabriel handled the desk. He searched now as he imagined it had been searched in the hours after Claudia’s death—drawer by drawer, file by file, page by page. Despite his thoroughness, he found nothing to indicate why anyone might want to kill her.
    But the men who had come before Gabriel had indeed made one mistake; they had left the building without emptying Claudia’s mailbox. Now Gabriel withdrew the post from Chiara’s handbag and quickly flipped through it until he found a credit card bill. The charges were a glimpse into a typical Roman life, preserved forever, like archaeological debris, in the memory banks of a mainframe computer. All the expenditures appeared unremarkable except for one. Two weeks before her death, it
