"I believe I can guess," quietly replied the cripple.

"That bill will tell you. This estate owes me five thousand, six hundred dollars, not counting later interest. I need the money. Can you pay it to-day?"

"Mr. Black, you know I cannot. It is simply impossible. I am trying to get affairs straightened up so that I can settle father's debts, but I am not quite ready."

"Make him pay or threaten to sue," muttered Ralph, in a voice intended for his father's ears.

Grant overheard the words, however. His eyes, generally so gentle, flashed, and he turned sharply on the ill-favored youth.

"I am conducting this conversation with Mr. Black," he said, sternly. "I understand why this note has been presented to-day. It is your doings. Simply because you had a quarrel with my brother, and he threatened to chastise you, you retaliate by demanding this money. If the truth was known, the entire debt was paid by my father on the day of his death."

For a moment a silence death-like in its intensity followed this bold speech. Father and son glared at Grant as if hardly believing their ears. The elder merchant's pallor seemed to increase, and he furtively moistened his lips with his tongue.

Ralph's face paled, and then flushed until the cords stood out in his forehead. Clinching his fists he strode over to where the cripple was standing near the bamboo desk.

"What's that you say?" he demanded, hoarsely. "Do you know what you mean, you puny wretch? It is an accusation of fraud, that's what it is. Retract those words, or I'll cram the lie down your throat."
