A Lesson in Murder:
When Jack and Sarah are called in to investigate mysterious pranks at Cherringham Girls School, it seems at first that it might be the work of a few mean pupils with a grudge. But things quickly turn serious when a popular teacher meets a sudden, violent death.
The Secret of Combe Castle:
When the penniless FitzHenrys find themselves victims of a threatening campaign to oust them from their ancestral home, Jack and Sarah are called in to track down the culprit. Soon, they discover that truth is often stranger than fiction, and in Combe Castle, things do indeed go bump in the night...
A Fatal Fall:
Dylan McCabe - a laborer on a rushed Cherringham building project - has been complaining about the site's lack of safety. When he's discovered dead after a fall, it seems that Dylan's own warnings are all too true. Jack and Sarah get involved, and suddenly, what looks like an accident becomes a case of cold-blooded murder.
I enjoy these stories immensely. It's nice to pick up with Jack and Sarah and follow them as they solve the mysteries of Cherringham residents.
