Arthur Conan Doyle has just killed off Sherlock Holmes in "The Final Problem," and he immediately becomes one of the most hated men in London. So when he is contacted by a medium "of some renown" and asked to investigate a murder, he jumps at the chance to get out of the city. The only thing is that the murder hasn't happened yet — the medium, one Hope Thraxton, has foreseen that her death will occur at the third séance of a meeting of the Society for Psychical Research at her manor house in the English countryside.Along for the ride is Conan Doyle's good friend Oscar Wilde, and together they work to narrow down the list of suspects, which includes a mysterious foreign Count, a levitating magician, and an irritable old woman with a "familiar." Meanwhile, Conan Doyle is enchanted by the plight of the capricious Hope Thraxton, who may or may not have a more complicated back-story than it first appears. As Conan Doyle and Wilde participate in séances and consider the possible motives of the assembled group, the clock ticks ever closer to Hope's murder, in The Revenant of Thraxton Hall by Vaughn Entwistle.
