Twelve-year-old Myrtle Hardcastle has a passion for justice and a highly unconventional obsession with criminal science.

Mr. Hardcastle’s pursuit of the case takes a detour when he’s hospitalized for a tonsillectomy—only to witness a murder. But where’s the victim? And who at the hospital could be harboring murderous intent? Myrtle is determined to find out before the killer comes after her father.

When her governess inherits an estate on a Scottish island, amateur detective Myrtle Hardcastle couldn't be more excited. Unfortunately, the ancestral castle is both run-down and haunted.

But who had the motive, means, and opportunity to kill him? And could this Scottish trip mean the end of Myrtle's plans to get her father and governess together?
