Members of the Lewes Bonfire Society would say afterwards that the event would have been a huge success that year, if it hadn’t been for the dead body… When the charred remains of MP Rupert Millington are found inside a burning effigy, no one knows how they got there, but there are plenty of rumours about whodunnit. The lead suspect wants Detective Tess Fox and her con-artist sister Sarah Jacobs to help clear her name. She says she's being framed, but surely there is no smoke without fire. The heat is on when a second victim is killed in a locked room while Tess and Sarah are in the building. Can the duo solve this puzzling mystery and find the real killer before they strike again?
