What happens
Inspector French, interrupted during supper, learns from Constable Caldwell that the woman from the circular has been identified as Mrs. Henry Vane of Crewe Lodge in St. John's Wood. French visits the house, finds it deserted with signs of a hasty departure, and interviews a neighbor's maid who reveals that Mrs. Vane left suddenly after receiving a cable about her husband's accident in New York. French then confirms with Mr. Williams that Mrs. Vane is the same woman who swindled him as Mrs. Root. Returning to Crewe Lodge, French and his team conduct a meticulous overnight search, finding evidence of a sudden flight about four days earlier but no trace of Mr. Vane.
