The Clock Strikes Thirteen

In Short

In Mildred A. Wirt's fast-paced 1942 mystery The Clock Strikes Thirteen, teenage sleuth and amateur reporter Penny Parker investigates a series of suspicious incidents plaguing the agricultural community of Riverview. After a local barn burns down under questionable circumstances, Penny uncovers a conspiracy involving masked night riders, a fraudulently sold camp property, a missing orphan, and a mysterious thirteenth stroke ringing from the municipal clock tower. Through quick thinking and daring intervention, Penny unmasks the criminal network behind the town's troubles. The book endures as a vivid slice of mid-century juvenile detective fiction, celebrating youthful ingenuity, resourcefulness, and journalistic determination.

The Story

The narrative opens late at night as Penny Parker visits her father, Anthony Parker, editor of the Riverview Star. Driving home through the surrounding agricultural country, they spot a blazing barn owned by local melon growers, the Prestons. They attempt to help save a truck from the flames, but the barn burns to the ground. When Sheriff Daniels arrives, he discovers a black hood in the nearby stable, immediately suspecting local farmer Clem Davis of being involved with a gang of night riders. Penny, however, doubts the obvious evidence, suspecting a setup to frame Davis.

Determined to dig deeper, Penny begins investigating the local mystery of the Hubell Clock Tower. The tower's newly installed caretaker, Charley Phelps, angrily denies that the clock ever rings improperly, but Penny remains skeptical, especially after learning that respected long-time caretaker Seth McGuire was abruptly replaced. Meanwhile, the night riders strike again, targeting melon farmers and disrupting local agricultural operations. When Penny and reporter Jerry Livingston organize a melon party for children from the Riverview Home at the Davis farm, hooded men on horseback raid the property. Penny and the orphans fight back by pelting the attackers with over-ripe cantaloupes, unseating one of the riders.

Complications multiply when young Adelle, an orphan from the home, runs away. Later, during a lake outing for the children, an overturned boat puts several orphans in danger. An unshaven man—whom Penny recognizes as the hiding Clem Davis—heroically dives into the water to rescue Adelle before disappearing into the woods. Upon her rescue, Adelle points an accusing finger at Clyde Blake, a prominent real estate agent and camp organizer, claiming his car killed her parents.

Connecting the threads, Penny tracks down Clem Davis, who reveals that the night riders, known as the Hoods, use the Hubell Clock Tower for secret meetings, signaling extra sessions by ringing the clock thirteen times at midnight. Penny also discovers that Clyde Blake is operating under false records to defraud the Camp Board on a real estate transaction, working alongside a notorious forger named Ben Bowman.

With her father and a crew of Star reporters, Penny stages a daring trap. Taking control of the clock tower mechanism, they force the bell to strike thirteen times at midnight. The signal draws the unsuspecting members of the Hoods directly into the waiting hands of the newsmen and police. During the chaos, Penny identifies the fleeing leader of the Hoods as Clyde Blake by his distinct physical deformity. The police arrest Blake and his co-conspirators, clearing Clem Davis's name and securing the city's camp property.
