Careful--morbidly careful, perhaps--not to attract attention needlessly to himself, he stopped the cab at the entrance to Redburn Road, and approached Number Five on foot. A servant-girl answered the door. Mountjoy asked if Mrs. Vimpany was at home. The girl made no immediate reply. She seemed to be puzzled by Mountjoy's simple question. Her familiar manner, with its vulgar assumption of equality in the presence of a stranger, revealed the London-bred maid-servant of modern times. "Did you say _Mrs._ Vimpany?" she inquired sharply. "Yes." "There's no such person here." It was Mountjoy's turn to be puzzled. "Is this Mr. Vimpany's house?" he said. "Yes, to be sure it is." "And yet Mrs. Vimpany doesn't live here?" "No Mrs. Vimpany has darkened these doors," the girl declared positively. "Are you sure you are not making a mistake?" "Quite sure. I have been in the doctor's service since he first took the house." Determined to solve the mystery, if it could be done, Mountjoy asked if he could see the doctor. No: Mr. Vimpany had gone out. "There's a young person comes to us," the servant continued. "I wonder whether you mean her, when you ask for Mrs. Vimpany? The name _she_ gives is Henley." "Is Miss Henley here, now?" "You can't see her--she's engaged." She was not engaged with Mrs. Vimpany, for no such person was known in the house. She was not engaged with the doctor, for the doctor had gone out. Mountjoy looked at the hat-stand in the passage, and discovered a man's hat and a man's greatcoat. To whom did they belong? Certainly not to Mr. Vimpany, who had gone out. Repellent as it was, Mr. Henley's idea that the explanation of his daughter's conduct was to be found in the renewed influence over her of the Irish lord, now presented itself to Hugh's mind under a new point of view. He tried in vain to resist the impression that had been produced on him. A sense of injury, which he was unable to justify to himself, took possession of him. Come what might of it, he determined to set at rest the doubts of which he was ashamed, by communicating with Iris. His card-case proved to be empty when he opened it; but there were letters in his pocket, addressed to him at his hotel in London. Removing the envelope from one of these, he handed it to the servant: "Take that to Miss Henley, and ask when I can see her." The girl left him in the passage, and went upstairs to the drawing-room.
