"That is the window of Mr. Ellerslie's study," he resumed. "You can see by the light shining through the circular openings at the top of the shutters that he is still at work." "That may be," rejoined the other, "but doubtless all his household are asleep long ago, and rather than disturb Mr. Ellerslie himself at such an hour I would----" "What a fastidious young cock-o'-wax you are!" broke in the elder man. "Do you think I would have brought you here if there had been nobody but Mr. E. to the fore? As I happen to know, his old manservant never on any account goes to bed before his master. Him we shall find as wide awake as an owl at midnight. Follow me." He led the way back to where a ramshackle, loosely-hung gate, merely on latch, gave admittance to a gravelled path which led up to a small carriage-sweep in front of the house, on reaching which, at the instance of the highwayman, they both dismounted. Then going up to the door, he lifted the massive knocker and struck three resounding blows with it slowly one after the other; after which, going back to his companion, he said, "Here, young sir, we must part." "But not, I trust, before you have told me to whom I am indebted for the very great service you have rendered me to-night." A bitter laugh broke from the other. "My real name," he said, "is that of a broken and ruined man, whom the world already has well-nigh forgotten. That by which I am customarily known nowadays is--Captain Nightshade, at your service." The younger man showed no trace of surprise. "I suspected as much from the first," he said. "In this part of the country only one _gentleman_ of the road does us the honor of taking toll of us. The rest are scum--mere vulgar ruffians, ripe for the gallows-tree." "Sir, you flatter me"--with a grave inclination of the head. "May I, in my turn, if it be not deemed an impertinence, ask to whom I am indebted for an hour of the pleasantest companionship it has been my good fortune to enjoy for many a long day?" "_My_ name? Hum! I must consider. By the way, you remarked a little while ago, and very truly, that, as far as your profession was concerned, I was a prentice hand. Suppose, then, that you call me Jack Prentice. 'Twill serve as well as another." "Mr. Jack Prentice let it be, with all my heart. 'Tis a name I shall not forget. Ah! here comes somebody in answer to my summons." And, indeed, there was a noise as of the undoing of the bolts and bars of the massive door, which, a few seconds later, was opened wide, disclosing a gray-haired serving-man in a faded livery, who stood there staring into the darkness, shielding with one hand a lighted candle which he carried in the other. Captain Nightshade strode up to the door, and in his easy, off-hand way said, "You are one of Mr. Ellerslie's servants, I presume?" "I be," answered the old man laconically.
