Little War in London

After an acrimonious US election whose outcome Moscow may or may not have influenced, can it really be that a few maverick intelligence agents from Russia and the United States are fighting a discreet battle-to-the-death on some of London's back streets? And that the corpses are piling up, out of sight of the British police?
Or is that just more "fake news"?
... Well, luckily, no it isn't. Not yet, anyway, because the media still hasn't heard about it. But that could change. When MI7 agent John Mordred is assigned to investigate, he uncovers a veritable Schrödinger's Cat state of affairs in which the relevant facts are neither wholly present nor entirely absent. And where some of the evidence lies closer to home than is comfortable.
Along the way, he is forced to address one of history's oldest questions. Just what is the truth anyway, and why do we care?
