Case of the Highland House Haunting

When Jillian Cooper purchased one of Pomme Valley's historic properties, Highland House, little did she know a violent murder happened there over 70 years ago. Tasking Zack and the dogs with disproving the rumors Dame Highland's ghost walked the halls, guarding her long hidden treasure, Jillian moves forward with her plans to turn the historic house into a bed and breakfast. However, when an "accident" claims the life of a contractor, it becomes apparent that someone doesn't want people snooping around the house. Can Sherlock and Watson, along with their pack of humans, prove the ghost is a fake? Will the corgi crime fighters put a stop to the shenanigans before another tragedy can happen?
