Putin and the Russians have suffered too many killings of their own people in the past. Now they want the whole of the 'Prime Minister's private army' wiped out, including Blake Johnson and Charles Ferguson. Somebody is after them

An unlikely man, brilliant and terrifying, ingenious and deadly, he is the wolf at the door.
