A family outing turns into an emergency when someone notices Mr. Lester’s car has been tampered with. Panic follows—“That brat ruined my plan!”—but Mabel’s prompt warning keeps Mr. Lester and Ms. Lester from riding and likely saves them. The household learns Mabel earlier rescued Mr. Lucas’s son; Mr. Lucas repaid that debt by dropping grudges and sending men to arrest the rumor-spreading Lewises. Praised as the family’s lucky star, Mabel is celebrated, yet the owner vows, “We will find out who did this,” leaving the saboteur hunt unresolved.
