Within weeks of leaving office, Mulroney was paid at least $225,000 in cash by Karlheinz Schreiber, an international arms dealer wanted in Germany for bribery and tax evasion. When confronted by Kaplan about the unexplained payment, Mulroney vehemently denied any wrongdoing: "Anyone who says anything about [the money] will be in for one fuck of a fight." At the root of Kaplan's investigation is a secret trial and its stunning revelations - information that nearly escaped public attention. Only now, years later, is the former prime minister facing a public inquiry that threatens to permanently derail his reputation.
