After the successful hardcover edition, The Spiritglass Charade is now a paperback!

Evaline Stoker and Mina Holmes never meant to get in to the family business, but after the Affair of the Clockwork Scarab, they are eager to help Princess Alix with a new case close to
her heart. Seventeen-year old Willa Aston is obsessed with spiritual mediums, convinced she is speaking with her mother from beyond. What seems like a case of spiritualism fraud quickly devolves into something far more sinister: someone is trying to make Willa ‘appear lunatic,’ using an innocent-looking spiritglass to control her. The list of clues piles up-an unexpected murder, a gang of pickpockets, and the return of vampires to London-but are these events connected? As Uncle Sherlock would say, ‘there are no coincidences.’ It will take all of Mina’s wit and Evaline’s muscle to keep London’s sinister underground at bay.
