A mathematician's murder draws Toronto PI Neil Walker into a web of Ponzi schemes, political corruption and global cybersecurity nightmares. Walker, an ex-RCMP financial-crimes specialist, has out-fought warring bikers and put Mafia dons behind bars. Now he's forced to work with Carole Lisgar, a high-powered political operator he once arrested for corruption. As more bodies drop and the stakes ramp up, Walker uncovers a conspiracy that stretches from Parliament Hill in Ottawa to a beach-front estate outside New York City and the devastated villages of earthquake-shattered Haiti. Fans of Robert B Parker's Spenser and Robert Crais's Elvis Cole won't want to miss this riveting tale of high finance, low morals and international secrets.
