Betrayed by the Truth - Daniella Bernett

An inconvenient alibi...a priceless treasure...an MI6 mole

It's a lethal cocktail

  Journalist Emmeline Kirby and her jewel thief/

insurance investigator husband Gregory Longdon become targets after a desperate stranger asks them to deliver a fortune in rare red diamonds to hotelier Alexander Colefax. Before they can ask any questions, the man is killed. 

Driven by dark secrets, Colefax is willing to flirt with treason if it means getting what he wants. His coterie included the son of a Kremlin elite and a Russian mafia boss. When a man's only loyalty is to money, his enemies become twice as ruthless. After Colefax is bludgeoned to death, Emmeline and Gregory discover that his dangerous games involved not only diamonds, but a stolen Fabergé egg that has vanished and a spy named Snowdrop. The trail of lies and revenge leads to Switzerland, where a treacherous double-cross could cost Emmeline and Gregory their lives.
