"Already done! I do not understand you, Mr. Harrison."
"Did I not pay you thirty thousand dollars a few weeks ago?"
"Yes, but not on this account."
"And did you not then give me a receipt in full of all demands, past, present, and to come?"
The face of Dunbar became pale, and his lips quivered.
"Was it just in you, sir," he said sternly, "to take that advantage of my ignorance of your relation to my intended wife?"
"Was it just in you, sir," returned Mr. Harrison, with equal sternness, "to take a bribe for the betrayal of your client, whose cause you might have gained?"
"It was as right as for you to offer it," retorted Dunbar.
"You are answered," said the old man, coldly. "I have your receipt, and mean to hold it against you."
"But do you think I will not cite you before the court to answer in this matter?" returned the lawyer. "The receipt was fraudulently obtained and cannot stand. Its very tenor expresses its character. I will swear that you refused to pay me a sum of money due, unless I would sign the receipt you have produced."
