This article: As part of a plan to launder billions of dollars in London, "the Prince" – the head of the Russian Mafia – creates a new bank and has its financial oligarchs sign over their accounts to him. The first oligarch to do so is murdered alongside his family by a blue-eyed assassin. Poetics lecturer Perry MacKendrick  and his barrister wife Gail are on a holiday in Morocco to try and salvage their marriage after Perry slept with one of his students. Perry strikes up a friendship with Dima, a hearty and boisterous Russian with an eidetic memory. The two men bond over drinks and tennis before Dima invites both MacKendricks to his daughter's birthday. At the birthday party, Dima gets Perry alone and gives him a USB stick that links corrupt British politicians and businessmen to the Russian mafia. He fears for his life after hearing of his fellow oligarch's fate, and pleads with Perry to turn the USB stick over to MI6 when he returns to London. Perry turns the information over to MI6 agent Hector, the investigator in charge. The information provided by Dima enables Hector and his supervisor Billy to witness a meeting between the Prince and corrupt politician Aubrey Longrigg. Billy refuses to sanction an investigation on a chance meeting. Hector continues regardless and recruits the MacKendricks to help stage a chance encounter with Dima in France. There, Dima provides all the names of his clients and confirms each banker and politician involved has received £5 million each for their endorsement of the new bank, with Longrigg receiving £30 million. Dima refuses to provide the bank account numbers that would verify the corruption until he and his family have been granted asylum in London. contains an answer for the question: How does Gail's husband give the information to Hector?, what is it ?
