The Crimson Thread: An Adventure Story for Girls

In Short

This 1925 juvenile mystery follows Lucile Tucker, a young clerk in a bustling Chicago department store, who finds herself caught up in a series of strange occurrences during the holiday rush. Between protecting her impulsive roommate Cordie, tracking down a mysterious local benefactor known as the "Spirit of Christmas," and avoiding shadowy figures in pursuit of a valuable iron ring, Lucile navigates the urban landscape of the 1920s. With its lighthearted pace, classic retail background, and interweaving subplots, it has endured as a charming example of early twentieth-century series fiction for young readers.

The Story

The adventure begins late at night inside one of the world's largest department stores, where Lucile Tucker works in the book department. Two hours before midnight, she spots a strange, beautiful face framed in white fur at the end of a dark corridor. Terrified by the approach of the store's night watchman, Lucile panic-steps into an open elevator cage, which suddenly ascends on its own. She escapes onto an upper floor, but the encounter sets off a chain of mysteries that consume her during the frantic final days of the Christmas shopping rush.

Lucile soon rescues Cordie, an affectionate and mysterious young woman who faints in the Art Museum while being coerced by a man claiming to be her brother. Lucile takes Cordie in as a roommate, though Cordie remains tight-lipped about her past, her connection to a police horse named Dick, and her possession of a strange iron ring set with a diamond. At the same time, the entire city is enthralled by the newspaper reports of the "Spirit of Christmas," a wealthy woman who wanders the streets in various disguises, leaving behind a "crimson trail"—a bit of crimson thread drawn twice and tied—and promising a bag of gold to anyone who recognizes her.

Meanwhile, parallel storylines unfold involving other young workers and shoppers. Florence, a girl who looks remarkably like a young woman named Meg, seeks her own holiday surprise by purchasing a sealed bag "with contents, if any" at an unclaimed baggage auction. Her purchase draws the attention of a menacing man who pursues her through a blizzard to an abandoned vessel on the frozen lakefront, where Meg uses a heavy iron belaying pin to defend their shelter. In the store, Lucile's charming fellow bookseller, Laurie Seymour, mysteriously flees whenever a man named Sam appears.

As Christmas Eve reaches its climax, the disparate threads collide. The sinister figures pursuing Cordie's iron ring ambush her and a mounted police officer, Patrick O'Hara, shooting his horse and injuring Laurie in the struggle. A hawk-eyed villain is subdued by a resolute man in gray with the help of the police. Gathered safely together afterward, the true identities are revealed: Patricia Diurno, a famous concert pianist, is both the Mystery Lady and the Spirit of Christmas who swapped her white fur cape for Lucile's ordinary coat on that first night. Laurie reveals he is actually Jefrey Farnsworth, a bestselling author hiding from his pushy publisher's promotional tour to sell his own books directly over the counter. Florence's auction bag yields valuable antique etchings that secure her future and Meg's, closing the adventure on a triumphant Christmas note.
