The Holmes Factor

It's just weeks from the outbreak of the First World War, a conflict few expect to erupt.

If it does, Russia is pivotal. But Russia, having survived one abortive revolution, seethes with unrest.

Lenin, Trotsky, and Stalin plot a second. The hypnotic monk Rasputin has ingratiated himself sufficiently with the Tsar and Tsarina to dictate government policy.

Will Russia fight? Will the Romanov dynasty be overthrown? If they are, will Britain accept them in exile? To answer such questions - upon which British war policy depends - Sebastian Holmes, son of the legendary Sherlock Holmes, is despatched to St Petersburg, where he infiltrates the revolutionaries and the imperial court.
