1914. Belfast is still mourning its dead two years after the sinking of the Titanic. Against this backdrop, high society has become obsessed with spiritualism through seances that attempt to contact spirits from beyond the veil.

William is a man of science and a sceptic, but one night with everyone sat around the circle something happens that places doubt in his heart and a seed of obsession in his mind. Could the spirits truly be communicating with him or is this one of Kathleens parlour tricks gone too far?

Based on the true story of William Jackson Crawford and famed medium Kathleen Goligher, and with a cast of characters that includes Arthur Conan Doyle and Harry Houdini, West conjures a haunting tale that will keep readers guessing until the end.
