A medieval manuscript depicting modern aircraft ignites a dangerous quest through time and Scottish folklore. Mortimer Mortensen finds himself entangled in a historical enigma when a discovered manuscript reveals anachronistic drawings of airplanes. His investigation into its origins pits him against hostile locals, the complexities of a time paradox, and a formidable young witch named Blossom, forcing him to confront the boundaries of history and magic.

The premise suggests a narrative that balances historical intrigue with fantastical elements, likely appealing to readers who enjoy mysteries with a speculative twist. The inclusion of a time paradox and a witch points towards a complex plot that may explore causality and folklore. The conflict with local inhabitants and the witch indicates a story driven by action and suspense. The narrative framework appears to be third-person, following Mortimer's investigation.
