A monogram was engraved upon the metal: "D.v.T." She gazed at the mark fixedly and then picked up a brush that the Frenchwoman laid down.

Yes, the same monogram appeared upon the brush.
The sharp eyes of Cerise had noted these movements.

She was a little dismayed but not startled when Louise said, slowly: "'D.v.T.' stands for Diana Von Taer.

And it isn't likely to stand for anything else.

I think the mystery is explained, now, and my worst fears are realized.
