It was a question, the answer to which was by no means evident at a glance; and leaving Helen Cumberly face to face with this new and horrible truth which had brought Denise Ryland hotfoot from Paris to London, let us glance, for a moment, into the now familiar room of Detective-Inspector Dunbar at Scotland Yard.
He had returned from his interrogation of Brian; and he received the report of Sowerby, respecting the late Mrs. Vernon’s maid. The girl, Sergeant Sowerby declared, was innocent of complicity, and could only depose to the fact that her late mistress took very little luggage with her on the occasions of her trips to Scotland. With his notebook open before him upon the table, Dunbar was adding this slight item to his notes upon the case, when the door opened, and the uniformed constable entered, saluted, and placed an envelope in the Inspector’s hand.
“From the commissioner!” said Sowerby, significantly.
With puzzled face, Dunbar opened the envelope and withdrew the commissioner’s note. It was very brief:—
“M. Gaston Max, of the Paris Police, is joining you in the Palace Mansions murder case. You will cooperate with him from date above.”
“Max!” said Dunbar, gazing astoundedly at his subordinate.
