A Darker Place - Jack Higgins

A famous Russian writer and ex-paratrooper named Alexander Kurbsky is fed up with the Putin government and decides he wants to “disappear” into the West. He is under no illusions, however, about how the news will be greeted at home, having seen too many of his countrymen die mysteriously at the hands of the thuggish Russian security services, so he makes elaborate plans with Charles Ferguson, Sean Dillon, and the rest of the group known informally as the “Prime Minister’s private army” for his escape and concealment.
