Evelyn was adopted from an orphanage as a child by Songpa, a Thai drug lord. She learned five languages and trained in combat. As an adult, she became his most trusted living ledger, while publicly passing as his “girlfriend.” She fell in love with Lee Lok-ki, an undercover Hong Kong cop, but Songpa discovered their relationship. She threatened him with Swiss bank records and demanded a prisoner exchange. Songpa agreed to let Lee Lok-ki go to Thailand on a job. Evelyn did not know that a tracking chip was hidden in an old scar on the sole of her foot. The moment Lee Lok-ki entered the country, he was tracked. She cut open the sole of her foot and removed the chip, only to discover that the signal was still coming from the villa. The accounts, tracking device, mole, and old orphanage photos all came to light one after another. Evelyn decided to stop running. She would use the ledger Songpa feared most to turn the entire Golden Harbor operation upside down.
