An enjoyable installment in the Grayson novella series!
This one was more rooted in the ghostly realm and not the fantastical. It stayed to the main point of trying to figure out why Mary, Queen of Scots, was visiting Holyroodhouse. Some may think she's evil, but there's always two sides.
The children: P.C., Brady, and Pip are adorable as ever, but they had a small part to play in this story. Grayson or Mr. Straithmore, like the character he writes in his novels, is the hero and solves the mystery to the delight of everyone!
This book hinted at more otherworldy adventures, so I'm looking forward to reading more, if Coulter is willing to write them!
