Jimmy Jones' Puzzles: The Mystery of Blackhill Estate

Present day Scotland. Sir Doughty dies suddenly and leaves his entire estate to the National Heritage Society under the condition that the property is turned into a museum. A small team is sent by the British Museum to consider the proposal and to start preparations for the museum. It seems like a straight forward case and they do not anticipate any problems, but soon they encounter strange occurrences that they cannot explain. As they try to unravel the mystery, they find out that Sir Doughty had made a discovery at the mansion shortly before he died, but took the secret with him to the grave. Will they find out what Sir Doughty's secret discovery was? Will they be able to put an end to the rumours that the mansion is haunted? The race is on and the stakes are high, but will Jimmy and his team make a great discovery or will it slip through their fingers...?
