Mallory Scott is an espionage operative, working for the British government. She’s travelled all over the world, often going undercover and infiltrating criminal organisations in order to extract the intelligence needed to dismantle their operations and bring the perpetrators to justice. Given her usual targets are terrorists, people-traffickers, drug-traffickers and arms dealers, her latest assignment should be relatively simple. A small group of Brits is raking in serious money in the diamond-scamming business—and although their MO is theft and forgery, rather than hurting people, they still need to be stopped. But up until now, they’ve proved elusive—no one can catch them in the act, or find a shred of evidence against them.
