The baron called his wife and asked her. She replied:

“Mademoiselle went to the eleven o’clock mass with the children, as usual.”

“But before that?”

“Before that? No.... Let me see!... I was so upset by the theft ... but I remember now that, on the evening before, she asked permission to go out on Sunday morning ... to see a cousin who was passing through Paris, I think. But, surely, you don’t suspect her?”

“Of course not ... but I would like to see her.”

He went to Wilson’s room. A woman dressed in a gray cloth dress, as in the hospitals, was bending over the invalid, giving him a drink. When she turned her face Sholmes recognized her as the young girl who had accosted him at the railway station.

Alice Demun smiled sweetly; her great serious, innocent eyes showed no sign of embarrassment. The Englishman tried to speak, muttered a few syllables, and stopped. Then she resumed her work, acting quite naturally under Sholmes’ astonished gaze, moved the bottles, unrolled and rolled cotton bandages, and again regarded Sholmes with her charming smile of pure innocence.

He turned on his heels, descended the stairs, noticed Mon. d’Imblevalle’s automobile in the courtyard, jumped into it, and went to Levallois, to the office of the cab company whose address was printed on the paper he had received from Henriette. The man who had driven carriage number 8,279 on Sunday morning not being there, Sholmes dismissed the automobile and waited for the man’s return. He told Sholmes that he had picked up a woman in the vicinity of the Parc Monceau, a young woman dressed in black, wearing a heavy veil, and, apparently, quite nervous.

“Did she have a package?”

“Yes, quite a long package.”
