"So, you thought I didn't understand! You thought I'd got a brain like a peanut, and wouldn't drop onto your game or the trap you've set. You'd advance money--got from the slave-dealers to prevent the slave-trade being stopped! If Claridge Pasha took it and used it, he could never stop the slave-trade. If I took it and used it for him on the same terms, he couldn't stop the slave-trade, though he might know no more about the bargain than a babe unborn. And if he didn't stand by the bargain I made, and did prohibit slave-dealing, nothing'd stop the tribes till they marched into Cairo. He's been safe so far, because they believed in him, and because he'd rather die a million deaths than go crooked. Say, I've been among the Dagos before--down in Mexico--and I'm onto you. I've been onto you for a good while; though there was nothing I could spot certain; but now I've got you, and I'll break the 'perfect friendship' or I'll eat my shirt. I'll--" He paused, realising the crisis in which David was moving, and that perils were thick around their footsteps. But, even as he thought of them, he remembered David's own frank, fearless audacity in danger and difficulty, and he threw discretion to the winds. He flung his flag wide, and believed with a belief as daring as David's that all would be well. "Well, what wilt thou do?" asked Nahoum with cool and deadly menace. "Thou wilt need to do it quickly, because, if it is a challenge, within forty-eight hours Claridge Pasha and thyself will be gone from Egypt--or I shall be in the Nile." "I'll take my chances, pasha," answered Lacey, with equal coolness. "You think you'll win. It's not the first time I've had to tackle men like you--they've got the breed in Mexico. They beat me there, but I learned the game, and I've learned a lot from you, too. I never knew what your game was here. I only know that the Saadat saved your life, and got you started again with Kaid. I only know that you called yourself a Christian, and worked on him till he believed in you, and Hell might crackle round you, but he'd believe, till he saw your contract signed with the Devil--and then he'd think the signature forged. But he's got to know now. We are not going out of Egypt, though you may be going to the Nile; but we are going to the Soudan, and with Kaid's blessing, too. You've put up the bluff, and I take it. Be sure you've got Kaid solid, for, if you haven't, he'll be glad to know where you keep the money you got from the slave-dealers." Nahoum shrugged his shoulders. "Who has seen the money? Where is the proof? Kaid would know my reasons. It is not the first time virtue has been tested in Egypt, or the first time that it has fallen."
