"I said what is true, Cohen, but it is not my money that I have to deal with. I have brought fifty pounds with me; another man's money, entrusted to me for a special purpose, and which you can have at once if you will undertake a certain task and accept a certain responsibility. It is only out of my friendship for you, it is only because I know you to be so badly off that you hardly know which way to turn, it is only because Rachel is ill and requires what you can't afford to pay for, that it entered my mind to offer you the chance." "Fifty pounds would be the saving of me, Mr. Moss," said Aaron, in an agony of suspense. "It would restore my Rachel to health, it would bring happiness into my life. Surely Heaven has directed you to come to my assistance!" "You shall judge for yourself. Listen patiently to what I am going to tell you; it will startle you, but don't decide hastily or rashly. And bear in mind that what passes between us is not to be disclosed to another person on earth." CHAPTER XXI. OVER A BRIGHT CLOUD A BLACK SHADOW FALLS. Mr. Moss then proceeded to unfold the nature of the mission he had undertaken for Mr. Gordon, with the particulars of which the reader has been made acquainted in the earlier chapters of this story. Aaron listened with attention and astonishment: with attention because of his anxiety to ascertain whether the proposal was likely to extricate him from his cruel position, with astonishment because the wildest stretch of his imagination would not have enabled him to guess the purport of the singular disclosure. When Mr. Moss ceased speaking the afflicted man rose and paced the room in distress and disappointment. "I told you I should startle you," said Mr. Moss, with a shrewd observance of his friend's demeanour, and, for the good of that friend, preparing for a battle. "What do you say to it?" "It is impossible--impossible!" muttered Aaron. "I told you also," continued Mr. Moss, calmly, "not to decide hastily or rashly. In the way of ordinary business I should not, as I have said, have dreamt of coming to you, and I should not have undertaken the mission. But the position in which you are placed is not ordinary, and you are bound to consider the matter not upon its merits alone, but in relation to your circumstances. I need not say I shall make nothing out of it myself." "Indeed you need not," said Aaron, pressing Mr. Moss's hand. "Pure friendship has brought you here, I know, I know; but surely you must see that it is impossible for me to assume the responsibility." "I see nothing of the kind. Honestly and truly, Cohen, I look upon it as a windfall, and if you turn your back upon it you will repent it all your life. What is it I urge you to do? A crime?" "No, no, I do not say that. Heaven forbid!"
