The question was out at last. If he had put it a quarter of an hour earlier, Arthur Lisle would have answered it to his satisfaction, however little he relished its being put. But now it was not fated to have an answer. For on the very moment of its being put, there came interruption in a form which made the continuance of this momentous conversation impossible. A barouche with a pair of fine bay horses, a barouche on Cee-springs, sumptuously appointed, clattered up the street and to the common amazement of the two men stopped at the door. The footman sprang down from the box and, touching his hat to a lady who occupied the carriage, waited for her instructions. But she paid no heed to him. She leant over the side of the carriage and looked at the two men for a moment. Sarradet took off his hat. Arthur Lisle just stared at the vision, at the entire vision, the lady, the carriage, the footman--the whole of it. The lady's face broke into a bright smile of recognition. "I came to call on Mr. Arthur Lisle. You must be Arthur, aren't you?" she said. No, there was no possibility of Mr. Sarradet's getting his question answered now. CHAPTER VI A TIMELY DISCOVERY When Arthur ran down the step and across the pavement, to take the hand which his visitor held out to him over the carriage door, Mr. Sarradet bowed politely, put his hat on, and turned on his heel. He was consumed with curiosity, but he had no excuse for lingering. He walked up Bloomsbury Street and along the east side of Bedford Square. But then, instead of pursuing a north-westerly course towards his home, he turned sharply to the right and, slackening his pace, strolled along Montague Place in the direction of Russell Square. He went about twenty yards, then turned, strolled back to the corner of Bedford Square and peered round it. He repeated these movements three or four times, very slowly; they consumed perhaps six or seven minutes. His last inspection showed the carriage still at the door, though neither the lady nor Arthur was visible. Evidently she was paying a call, as she had intimated; no telling how long it might last! "Well, I must go home," thought Mr. Sarradet, as he strolled slowly towards the east once more. He turned and walked briskly back. Just as he reached again the corner from which he had taken his observation, he made a sudden backward jump. He was afraid that he was caught! For the barouche dashed by him at a rapid trot, and in it sat the lady and Arthur Lisle. They did not see him; their heads were turned towards one another; they appeared to be engrossed in a lively conversation. The carriage turned westward, across Bedford Square; Sarradet watched it till it disappeared round the corner into Tottenham Court Road.
