The Last Borrowed Page
A retired librarian volunteering at a seaside bookshop notices inconsistencies in ordinary records. A visiting dealer is found dead before revealing that a festival organizer sold a forged first edition.
- Opening: A retired librarian volunteering at a seaside bookshop notices inconsistencies in ordinary records. Establish a fictional seaside bookshop during a literary weekend.
- Disruption: A visiting dealer is found dead before revealing that a festival organizer sold a forged first edition.
- Turning point: A marginal note prompts the sleuth to compare two versions of a key document.
- Pressure: A nervous volunteer hides a private sale, drawing suspicion away from the organizer.
- Payoff: A print date in the alleged first edition disproves the organizer's account; corroborating event records establish the organizer as the culprit. Resolve the central conflict and pay off the planted details.
