"No. My interest in her ceased when I gave up the case as hopeless. I had fresh cases--new interests; and the murder of Marie Prévol remained in my mind only as a tradition, until you recalled the story of the crime." "I telegraphed yesterday to the principal of the Ursuline convent at Dinan," said Mr. Heathcote, "and I have obtained from her the address at which Madame Lemarque was living two years ago, when her niece was sent back to Paris in company with other pupils. After leaving you I shall go to that address, and try to find Madame Lemarque. I may have the painful duty of informing her of her granddaughter's death; and yet I can but think that were the grandmother still living she must have heard of the girl's death, and would have communicated with the Cornish police." "That is to suppose her more intelligent than the average Frenchwoman," said Drubarde, as if he belonged to another nation. "Suppose I accompany you in your search for Madame Lemarque? That ought to be interesting." "I shall be delighted to secure your aid." Monsieur Drubarde and his guest descended the ladder. The detective put on a gray overcoat, which concealed and subjugated the airiness of his summer attire. He put on the hat of sober commonplace existence, and contrived to give himself an almost patriarchal aspect before he left his lodging. The street in which Madame Lemarque had been living when the nuns of Dinan last heard of her was a narrow and shabby little street between Saint-Sulpice and the Luxembourg. The house was decently kept, and had a respectable air, and was evidently not one of those caravanserais where lodgers come and go with every term. It had a settled sober appearance, and the brass plates upon the door told of permanent residents with reputable avocations. One of these plates informed society that Mesdames Lemarque and Beauville, _Robes et Modes_, occupied the third floor. The staircase was clean and quiet, and the first sound that saluted Mr. Heathcote's ears as he went up-stairs was the screech of a parrot, which became momentarily louder as the visitors approached the third floor. On the door on the left of the landing appeared another brass plate--Mesdames Lemarque et Beauville, Robes, Modes, Chapeaux. Heathcote rang the bell. He felt curiously agitated at the thought that in the next minute he might be face to face with the dead girl's grandmother. The door was opened by an elderly woman in black, very sallow, very thin, with prominent cheekbones and hungry black eyes. She was neatly clad, her rusty silk gown fitting her fleshless form to perfection, her linen collar and cuffs spotlessly clean, her iron-gray hair carefully arranged; but poverty was stamped upon every fold of her gown, and written in every line upon her forehead. "Madame Lemarque?" inquired Heathcote, while the _ci-devant_ police-officer looked over his shoulder.
