‘He never deceived me,’ said Aleksei. ‘He just persuaded me to deceive myself.’ His eyes flicked up and looked straight into hers. ‘But I’ve understood the truth for a long time. Some things don’t need faith – some things you just know.’

Domnikiia had no idea what he was talking about, but she saw the look of love in his eyes, the same look she had seen every day since she had climbed out of that troika after a journey of thousands of versts and their eyes had met for the first time in two years. She did not care to listen to their conversation any more; she did not need to.

She went back outside and walked slowly, with a little pain in her knees, back to her chair. She sat down and gazed up above her. There was no moon tonight, but the sky glittered. It was strange, but she sat out there most nights – when it was neither cold nor cloudy – and gazed at the constellations, most of which Aleksei had taught her. He was smart enough to know that the patterns were just random, not icons set into the sky by the gods, and she was smart enough to believe him, but it wasn’t for that that she gazed at them.

Her reasoning was simple. It wouldn’t be every night, it probably wasn’t tonight – it might only be one in a hundred or even a thousand nights – but just occasionally, Domnikiia was sure, as she looked up at Pegasus or Orion or Cassiopeia, that somewhere, across half a continent, her daughter would be walking along a street, or sitting in a chair, or lying in a bed with the man she loved, and lifting her eyes skyward to gaze, like her long-forgotten mother, upon those same stars.

The official record tells us that Tsar Alexander I entered immortality in Taganrog on 19 November 1825, attended by his wife and his closest advisors. But almost immediately, rumours began to circulate that he had not died but had faked his own death, in order to abdicate a crown with which he had never felt comfortable. The tale was that he lived out the remainder of his long life in the guise of an impoverished holy man, by the name of Fyodor Kuzmich, dying finally in Tomsk in 1864. If Alexander and Kuzmich were one and the same, then he would have been eighty-six years old. While many historians regard these stories as worth little more than a footnote, within the Romanov family itself they were widely held to be true. As recently as 1958, the Grand Duchess Olga Alexandrovna, sister of the last tsar, Nicholas II, is quoted as saying, ‘I am old and not long for this world; you are young and apparently have understanding of these things. You should know that we have no doubt that Fyodor Kuzmich was the emperor.’

Born in Worcestershire in 1968, Jasper Kent read natural sciences at Cambridge before embarking on a career as a software consultant. He also pursues alternative vocations as a composer and musician and now novelist.

The inspiration for Jasper’s bestselling début, Twelve (and indeed the subsequent novels in The Danilov Quintet), came out of a love of nineteenth-century Russian literature and darkly fantastical, groundbreaking novels such as Frankenstein and Dracula. His researches have taken him across Europe and to Saint Petersburg, Moscow and the Crimea, including three days on a train from Cologne to the Russian capital, following in the footsteps of Napoleon himself.

Jasper lives in Brighton, where he shares a flat with his girlfriend and several affectionate examples of the species rattus norvegicus.
