When Dimitri, a London-based Russian financier, is murdered, only Nat Geo documentary maker Lauren Eaves can provide desperately-needed answers to halt an imminent nuclear terrorist threat to vaporise London – but Lauren is missing.

My novel is a dual-timeline present-day Cold War thriller. I've carried out extensive research into the KGB, FSB, and senior Russian figures, past and present. I'm now getting hits on my website from Russia - should I be worried!? 😮 I also refer to Putin in my book; should I invent a new fictional Russian leader? Putin is not a character; he is only mentioned in passing.

@Issy McCann how many words in would you suggest is the maximum before an inciting incident should occur?
