Chapter 1: The Invitation

The envelopes arrived simultaneously at five different addresses across three time zones, each one hand-delivered by a courier in a grey suit who departed without waiting for a reply. Inside each envelope was a single card printed on stock so heavy it felt like metal, bearing an address, a time, and a six-digit number unique to the recipient. No name. No explanation. No return address. Maren Alsvik received hers in Oslo while reviewing blueprints for a bank she had no intention of robbing through the front door. She was an architect by training and a vault designer by obsession, which made her one of the few people alive who understood that most security systems failed not because of bad engineering but because of predictable human behavior. The six-digit number on her card was the combination to a safe she had designed three years ago for a client in Zurich. A safe that, to her knowledge, had never been opened by anyone other than its owner. That detail convinced her to attend. Tomasz Wren found his card pinned beneath the windshield wiper of a car he had stolen forty minutes earlier in Prague. His number was the serial code of the first forged passport he had ever created, a document so perfect it had fooled border agents in eleven countries before he retired it out of sentimental attachment. Yuki Sato discovered hers slipped inside a library book in Kyoto. Devonte Ellis opened his taped to the underside of a park bench in Atlanta. Lian Zhou pulled hers from a fortune cookie at a restaurant in Shanghai where she had been conducting surveillance on an unrelated target. Five strangers, each possessing skills that complemented the others with surgical precision. Five numbers that demonstrated the sender knew things about them that should have been unknowable. They arrived at the address on a Tuesday night and found a windowless building, a steel door, and a countdown clock on the wall that read twelve hours.
