"How clumsy of me!" exclaimed Madame in some confusion, whilst the commissary of police, agitated and obsequious, crawled about on his hands and knees, trying to collect the fragments of priceless china which littered the carpet. "Do not trouble, I pray you, Monsieur le Commissaire," said the Marquise with affable condescension. "The servant will clear away the rubbish."

She sank into a chair, as if tired out with the interminable interview, and put her aristocratic hand up to her mouth, smothering a yawn.

"As you were saying, Monsieur—er——" she drawled wearily.

"I was not saying anything, Madame la Marquise," rejoined the Man in Grey, smiling.

"Your spy or messenger, whatever he was——" interposed the Marquis impatiently. "You were saying something about him."

"Oh! nothing that would interest Monsieur le Marquis," replied the secret agent. "He was stabbed in the hand with a pin steeped in a deadly arrow poison, which in ordinary circumstances would have killed him in less than five minutes. Fortunately for him the assassin was either inexperienced or clumsy, or perhaps the poison had become stale by keeping. At any rate, poor Hippolyte Darnier was nearly killed—but not quite. He is still very ill—half paralysed; but the leech assures me that he will recover."

This time there was no mistaking the shadow which once more passed across the Marquise's handsome face, whilst for the space of a second or two the somewhat high colour of her cheeks changed to a leaden hue. The Marquis instinctively came forward a few steps, obtruding his stately figure between the police agent and his wife. Next moment, however, Madame had regained her composure. She rose from her chair, tall, dignified, unspeakably haughty.

"So much the better for your friend, Monsieur—er—I forget your name," she said coldly. "And now," she added as she walked majestically towards the door, "if you or Monsieur le Commissaire have any more senseless questions to ask, you must be content with the information Monsieur le Marquis condescends to give you. I confess to being weary of this folly."

She pushed open the door and sailed out of the room, as arrogant as any Queen of the old régime dismissing an importunate courtier. Then the door fell to behind her and her firm step soon died away along the marble corridor.
