THE RUSSIAN BANK-NOTES The three searchers into what was rapidly becoming a most complicated mystery drove back to New Scotland Yard in a silence which lasted until they were set down at the door of the department whereat they had interviewed the high official.

Celia Lennard was thoroughly upset; the sight of the dead woman had disturbed her even more than she let her companions see; she remained dumb and rigid, staring straight before her as if she still gazed on the white face set in its frame of dark hair.
Allerdyke, too, stared at the crowds in the streets as if they were abstract visions--his keen brain felt dazed and mystified by this accumulation of strange events.

And Fullaway, active and mercurial though he was, made no attempt at conversation--he sat with knitted forehead, trying to think, to account, to surmise, only conscious that he was up against a bigger mystery than life had ever shown him up to then.
The detective who had accompanied them to the mortuary conducted the three straight back to his chief's office--the chief, noticing the effect of the visit on Celia, hastened to give her a chair at the side of his desk, and looked at her with a lessening of his official manner.

He signed to the other two to sit down, and motioned the detective to remain.

Then he turned to Celia.
"You recognized the woman ?" he said softly.
