An almost imperceptible shadow seemed to pass as in a flash over the Marquise's handsome face; but the very next second she shrugged her handsome shoulders and said flippantly:

"The same thing, my good man."

"I trust not, Madame la Marquise," rejoined the Man in Grey.

"Oh, we all know," here interrupted M. le Marquis with a sneer, "that in your unavowable profession, Monsieur, you are bound to send a certain number of unfortunates to what you call justice, whether they are guilty or not, or you would lose your highly lucrative employment. Isn't that so?"

"Our employment, Monsieur le Marquis," replied the Man in Grey imperturbably, "is not likely to find favour in your sight."

"Well!" rejoined Madame with a harsh laugh, "so long as you don't trump up a charge of murder against some poor innocent this time——"

"Murder, Madame la Marquise!" queried the secret agent with a look of mild astonishment in his colourless eyes. "Who spoke of murder?"

"I thought," parried the Marquise airily, "that some spy or other of yours was murdered and robbed of the forged letter, which was supposed to convict Monsieur le Marquis de Trévargan and myself of disloyalty."

"One of our men was certainly robbed of a letter written by Monsieur le Marquis de Trévargan to Monsieur de Romorantin on the eve of the conspiracy against the Emperor," said the Man in Grey, "but I am happy to say that he is alive at the present moment——"

A terrific crash of broken china drowned the rest of his speech. The table against which Madame la Marquise had been leaning fell over, scattering precious bibelots in every direction.
