The Lost Engine: A Penrose Mystery

By J. Jasper North

When a century-old locomotive headlight turns up beneath a Penrose parking lot, bookseller Ari Penrose wants to know where it came from. A headlight means an engine. An engine means a line. And a line has to go somewhere.

What follows pulls Ari and his friends -- archivist Sophia Eden, geologist Jason Bloom, caf owner Clair Finch, and undergraduate Hannah Lewis -- into the strangest investigation Penrose has ever seen. The ground itself has something to say. So does the historical record, once Sophia starts asking the right questions. So do certain members of the town's Heritage Preservation Board, though what they're saying is: stop.

Penrose is a town that knows how to keep a story quiet. It's been doing it for a hundred and sixty years.

The Lost Engine is the fifth Penrose Mystery -- and proof that this town is nowhere near finished with its secrets.
