He rose from his seat, and came closer to Andre.

“Why on earth,” asked he, “should you daub all this color on your face, which makes you look like an Indian warrior in his war-paint?  Only two colors are necessary to change the whole face—­red and black—­at the eyebrows, the nostrils, and the corners of the mouth.  Look here;” and taking from his pocket a gold pencil-case, he corrected the faults in the young artist’s work.

As soon as he had finished, Andre went up to the mirror over the chimney-piece, and was surprised at the result.

“Now,” said the strange gentleman, “you see the futility of your attempts.  La Candele knew you at once.  I wished to speak to you; so I sent for Palot, one of my men, and instructed him to pick a quarrel with you.  The policemen arrested you, and we have met without any one being at all the wiser.  Be kind enough to efface my little corrections, as they will be noticed in the street.”

Andre obeyed, and as he rubbed away with the corner of his handkerchief, he vainly sought for some elucidation of this mystery.

The man with the gold spectacles had resumed his seat, and was refreshing himself with a pinch of snuff.

“And now,” resumed he, “we will, if you please, have a little talk together.  As you see, I know you.  Doctor Loulleux tells me that he knows no one so high-minded and amiable as yourself.  He declares that your honor is without a stain, and your courage undoubted.”

“Ah! my dear sir!” interposed the painter, with a deep blush.

“Pray let me go on.  M. Gandelu says that he would trust you with all he possessed, while all your comrades, with Vignol at their head, have the greatest respect and regard for you.  So much for the present.  As for your future, two of the greatest ornaments of the artistic world say that you will one day occupy a very high place in the profession.  You gain now about fifteen francs a day.  Am I correct?”

“Certainly,” answered Andre, more bewildered than ever.

The gentleman smiled.

“Unfortunately,” he went on, “my information ends here, for the means of inquiry possessed by the police are, of course, very limited.  They can only act upon facts, not on intentions, and so long as these are not displayed in open acts, the hands of the police are tied.  It is only forty-eight hours since I heard of you for the first time, and I have already your biography in my pocket.  I hear that the day before yesterday you were dining with M. de Breulh-Faverlay, and that this morning you were walking with young Gandelu, and that La Candele was following you like a shadow.  These are all facts, but——­”

He paused, and cast a keen glance upon Andre, then, in a slow and measured voice, he continued,—­

“But no one has been able to tell me why you dogged Verminet’s footsteps, or why you went to Mascarin’s house, or why, finally, you disguised yourself to keep a watch on the movements of the most honorable the Marquis de Croisenois.  It is the motive that we cannot arrive at, for the facts are perfectly clear.”
