"You are very good, Robert. I would rather see you spend it upon yourself; but, dear me, what a manager you must be to dress so beautifully as you do, and send your old father presents as you do, and yet put by fourteen hundred pounds to buy this living." "You are mistaken, sir, I have only saved four hundred; the odd thousand-- But that is a secret for the present." "Oh, I am not inquisitive. I never was." They then chatted about things of no importance whatever, and the old gentleman was just lighting his candle to go to bed, when a visitor was ushered into the room. The Penfolds looked a little surprised, but not much. They had no street door all to themselves; no liveried dragons to interpose between them and unseasonable or unwelcome visitors. The man was well dressed, with one exception; he wore a gold chain. He had a hooked nose, and a black, piercing eye. He stood at the door and observed every person and thing in the room minutely before he spoke a word. Then he said, quietly, "Mr. Michael Penfold, I believe." "At your service, sir. "And Mr. Robert Penfold." "I am Robert Penfold. What is your business?" "Pray is the 'Robert Penfold' at the back of this note your writing?" "Certainly it is; they would not cash it without that." "Oh, you got the money, then?" "Of course I did." "You have not parted with it, have you?" "No." "All the better." He then turned to Michael and looked at him earnestly a moment. "The fact is, sir," said he, "there is a little irregularity about this bill which must be explained, or your son might be called on to refund the cash." "'Irregularity about--a bill?" cried Michael Penfold, in dismay "Who is the drawer? Let me see it. Oh, dear me, something wrong about a bill indorsed by you, Robert?" and the old man began to shake piteously. "Why, father," said Robert, "what are you afraid of? If the bill is irregular I can but return the money. It is in the house." "The best way will be for Mr. Robert Penfold to go at once with me to the bill-broker; he lives but a few doors off. And you, sir, must stay here and be responsible for the funds, till we return." Robert Penfold took his hat directly, and went off with this mysterious visitor. They had not gone many steps, when Robert's companion stopped, and, getting in front of him, said, "We can settle this matter here." At the same time a policeman crossed the way and joined them; and another man, who was, in fact, a policeman in plain clothes, emerged from a doorway and stood at Robert Penfold's back. The detective, having thus surrounded him, threw off his disguise. "My man," said he, "I ought to have done this job in your house. But I looked at the worthy old gentleman and his gray hairs. I thought I'd spare him all I could. I have a warrant to arrest you for forgery!" "Forgery! arrest me for forgery!" said Robert Penfold, with some amazement, but little emotion; for he hardly seemed to take it in, in all its horrible significance.
