Publisher's Synopsis
Scotland, 1912: When Maud and Daisy travel to Clachan Castle on the Isle of Mull to investigate the theft of a valuable statuette, at first the case seems straightforward. But when their prime suspect, bad-tempered fellow guest Mr Tremain, is found dead in his bed, the detective duo realise the castle is under attack. At first, it appears the murder is impossible. All the doors and windows to the room were locked from the inside, and there was no way for the killer to escape. But then Maud and Daisy find a secret panel with the stolen statuette hidden behind it, and learn that the mysteries are linked! When the local sergeant investigating the case is found dead, the crime suddenly seems to have more twists and turns than the castle's sweeping staircases. And with the estate full of potential suspects, Maud and Daisy must work fast to uncover the murderer.
