The Duke bowed and left the room. The moment the door closed behind him he made the best of his way to the kitchen. A few words were enough to impart his suspicions to the policeman. A daring and ingenious scheme was evidently on foot, its object being the theft of the Queen Bess flagon. Even now, unless they acted quickly, the young man might lay hands on the cabinet in which the treasure lay and be off with it. In a trice the Duke had discarded the police uniform, its rightful owner had resumed it, and the Duke was again in the convenient black suit which befits any man, be he duke or valet. Then the kitchen window was cautiously opened, and the policeman crawled silently round to the front of the house; here he lay in waiting for a summons or for the appearance of a visitor. The Duke returned immediately to the sitting-room. On entering, he perceived the young man standing in front of the locked cabinet, and regarding it with a melancholy air. The Duke’s appearance roused him, and he glanced with visible surprise at the distinguished and aristocratic figure which the supposed policeman presented. But he made no comment and his first words were about the flagon. “Now I come to remember,” said he, “I put the Queen Bess flagon in this cabinet. It must be so, although, as I have left my key at my rooms in St James’s Street, I can’t satisfy myself on the point.” The Duke, now perfectly convinced of the character of his visitor, waited only to see him lay his hands on the cabinet. Such an action would be the signal for his instant arrest. But before the young man had time either to speak again or to put out his hand towards the cabinet, there came the sound of wheels quickly approaching the villa. A moment later a neat brougham rolled up to the door. The young man darted to the window, tore open the shutters, and looked out. The Duke, suspecting the arrival of confederates, turned towards the cabinet and took his stand in front of it. “Go and open the door,” ordered the young man, turning round. “Don’t keep the lady waiting outside at this time of night.” Curiosity conquered prudence; the Duke set more value on a night’s amusement than on the Queen Bess flagon. He went obediently and opened the door of the villa. On the step stood a young and very handsome girl. Great agitation was evident in her manner. “Is--is the Duke here?” she asked. “Yes, madam. If I lead you to the sitting-room, you will find him there,” answered the Duke gravely; and with a bow he preceded her along the passage. When they reached the room, the lady, passing by him, darted forward and flung herself affectionately into the young man’s arms. He greeted her with equal warmth, while the Duke stood in the doorway in some natural embarrassment. “I escaped so successfully!” cried the lady. “My aunt went to bed at eleven; so did I. At twelve I got up and dressed. Not a soul heard me come downstairs, and the brougham was waiting at the door just as you said.”
