Guy. Rebellion is in the air to-night. You've caught the prevalent disease, my Ruth. Ruth. Guy, this man means to kill you. Guy. I mean to kill this man. But I've a scruple that prevents my shooting down an unarmed man. Ruth. You're both safe then. Guy. Not while my pistol's left. He seems to think the luck is on his side. We'll put that to the test by tossing for the first shot. Ruth. But he might win. Guy. That will decide the point at issue. Luck will be on his side. You've got your chance now, Kelsall. (_Taunting him._) What was it? Oppressor and oppressed, avenger and avenged? Martin. My God, I wish I had your coolness. Guy. Blood will tell, you know. Do you accept? Martin (_in a rush_). Yes, I accept. Guy. Good. Shall I spin a coin or you? Martin. I don't bring money out. It's scarce with me. Guy. Then I provide both pistol and coin. Martin. And corpse. Guy. You're getting back your spirit. Will you call? (_He spins a coin. Ruth puts her foot on it as it falls. At the same time the moon lights up the scene._) Now that's really very thoughtful of the moon. The target will be visible, and we can see the coin as soon as you remove your foot. Ruth. I shall not remove my foot. Guy. And Kelsall quite forgot to call. He's too busy shivering. Martin. I'm cold. Guy (_taking another coin, spinning and catching rapidly_). This time, Kelsall. Martin. Heads. Guy (_looking_). The pistol's yours. (_Martin crosses doubtfully and takes it._) Oh yes, it's loaded. Ruth (_facing Martin, covering Guy, melodramatically_) Martin, you'll shoot him through my body. Guy. I'm sure that's out of Mrs. Radcliffe, Ruth. It has the true romantic ring. Will you help me to tie her up, Kelsall? It's a bore to have to ask the favour, but---- Martin. You're smiling and you're going to die. Guy. It's possible, but these cold nights do make a man's hand shake, don't they? Your luck may not be altogether in. The heavens do not send the sign you look for. Martin. They sent the moon to shoot you by. Guy. Yes. Get out of the way, Ruth, unless you want to be tied up. Stand clear. This fellow's hand's so shaky he might hit you by mistake. Go ahead, Kelsall. Remember your wrongs and your faith and blaze away. Martin (_half raising the pistol, then dropping it_). I can't do it. It's the chance I've prayed for and I can't do it. Guy. Oh come, Kelsall. Remember what's expected of a leader of the men. Martin (_jerking up his head_). I've beaten you there. Yes, now I understand. I'm not afraid to shoot. Guy. My mistake. Martin. Oh, I've a sweeter revenge than that, Shoot, and you'd never know the way that you've been fooled this night. Guy. You didn't shoot because you lacked the pluck. Martin. The thing I didn't lack was brain to outwit you and bring you on a fool's errand to the moors while---- (_Pausing._) Guy (_alarmed_). While what? Martin. Oh, while the moon came out and showed your military friends the truth.
