In 1920s London, “Lady Detective” Maud West enlists newly published Agatha Christie to covertly investigate a dangerous mystery, propelling the unlikely duo through mounting threats and blackmail in a quest to deliver justice.
In early 1920s London, Maud West has gained a public reputation as “London’s Lady Detective,” though the title is largely of her own making. Her self‑written newspaper accounts bring her notoriety, but not the professional respect she craves. Instead of high‑profile investigations, she is routinely assigned divorce work, missing persons, and blackmail—cases that rarely challenge her talents or elevate her status. When a frightened woman comes to her office claiming she is being stalked by a strange man, Maud senses a rare opportunity to prove her skill. As she digs deeper, she discovers that her client’s troubles are tied to a clandestine gang operating within the city. The threats quickly escalate, and soon Maud herself becomes a target.
Elsewhere in London, Agatha Christie is both a new mother and a rising author, thrilled to see her first detective novel in print. Yet she hungers to observe a real investigation firsthand. Maud West’s exploits in the newspapers captivate her imagination and fuel her desire to study genuine detective work.
To Agatha’s astonishment, she receives a message from Maud requesting a private meeting. Maud outlines the increasingly perilous case and proposes a partnership: As a public figure tied to the investigation, she needs someone inconspicuous and sharp‑minded to assist her. Agatha, a crime novelist rather than a known detective, is the perfect covert ally. Together, the celebrated detective and the rising mystery writer become entangled in a dangerous, twisting web that will test their ingenuity, courage, and trust as they work to bring justice to light.
