Chapter 1: The Handler

Katrin Engel had three rules for surviving in intelligence work: never trust a source you have not personally verified, never use the same dead drop twice, and never fall asleep in a location that only one person knows about. She had followed these rules for nineteen years across postings in Berlin, Istanbul, and Taipei, and they had kept her alive when colleagues with looser protocols had not been so fortunate. Now she sat in a cafe in Vienna, drinking coffee that was too strong and reading a newspaper that contained a coded message in the classified advertisements. The message was from her handler, a man she knew only as Callsign Grey, who had been running her operations from Langley for the past four years. Grey was requesting an emergency meeting, which had never happened before and which violated his own security protocols so flagrantly that it could only mean something had gone catastrophically wrong. She arrived at the meeting point, a bookshop on Josefsgasse, at the appointed time and found Grey standing in the philosophy section, pretending to read a volume of Kierkegaard. He was shorter than she had imagined from his voice on the encrypted line, with the unremarkable face of a man who had cultivated anonymity as a professional skill. 'We have a mole,' he said without preamble. 'Someone inside our European operations has been feeding intelligence to a hostile service for at least three years. We have lost four agents and two networks. The damage assessment is still growing.' 'How do you know it is European operations?' 'Because the leaked material matches a distribution list of seven people, and I need you to determine which one before the next operation goes live in eleven days.' Katrin closed the newspaper and folded it into her coat pocket. 'Give me the list.' Grey handed her a sealed envelope. 'The seventh name will surprise you,' he said quietly. 'It surprised me.' She opened the envelope in the taxi and read the seventh name. It was her own.
