Future president Theodore Roosevelt and his new wife, Edith, travel to London on their honeymoon in 1887. After a chance encounter with the Prince of Wales, they uncover a plot to assassinate Queen Victoria. When the criminals kidnap Edith to use as leverage, Theodore teams up with Inspector Frederick Abberline of Scotland Yard. Roosevelt discovers that Abberline's boss is one of the conspirators and that an Irish separatist group is behind the evil scheme. Roosevelt and Abberline learn that the would-be assassins are planning a deadly, explosive spectacle during the queen's Golden Jubilee celebration in hopes of destroying the British monarchy. Author Steven Wilson weaves fact and fiction together in this suspenseful historical novel set right before the turn of the century, when the British government is struggling to remain relevant. This is London just before Jack the Ripper terrorizes the city, as social classes battle and war looms on the horizon. As Theodore and Edith discover, it's a place where no one can be trusted and everyone has a second trick up his or her sleeve. And unless they can outwit the tricksters, the sun will be setting on the British Empire.
