Inspector French's Greatest Case

During Inspector French's brief lunch hour he continued turning over in his mind the immediate problem which Mr. Williams's story had raised for him, namely, at what point he had best attack his new inquiry.

The facts postulated a good deal of obvious detailed investigation, and he felt he should carry this through in his usual systematic way before attempting to evolve a comprehensive theory of the crime. He had first to learn what he could of the mysterious Mrs. Root, and in this connection he foresaw inquiries at Pittsburg, from the White Star people, from the Southampton police at the Savoy, and at the various firms of jewellers to whom the cheques had been made out. He had, if possible, to find the lady, or her impersonator. These things accomplished, he could turn his attention to an attempt to connect the person found with Miss Duke, or at all events with Mr. Duke's jewels, and subsequently with the murder of Charles Gething.
