She staggered, back toward the bed, whispering the words over and over again. Not until she had dropped upon it did Billy move. The blood in his body seemed to have turned cold. Be dropped upon his knees at her side. His hand buried itself in the soft smother of her hair, but he no longer felt the touch of it. He tried to speak, but words would not come. And then, suddenly, she thrust him back, and he could see the glow of her eyes in the half darkness. For a moment she seemed to have fought herself out of her delirium. "It was you-- you-- who helped to kill him!" she panted. "It was the Law-- and you are the Law. It kills-- kills-- kills-- and it never gives back when it makes a mistake. He was innocent, but you and the Law hounded him until he died. You are the murderers. You killed him. You have killed me. And you will never be punished-- never-- never-- because you are the Law-- and because the Law can kill-- kill-- kill--" She dropped back, moaning, and MacVeigh crouched at her side, his fingers buried in her hair, with no words to say. In a moment she breathed easier. He felt her tense body relax. He forced himself to his feet and dragged himself into the outer room, closing the door after him. Even in her delirium Isobel had spoken the truth. Forever she had digged for him a black abyss between them. The Law had killed Scottie Deane. And he was the Law. And for the Law there was no punishment, even though it took the life of an innocent man. He went outside. McTabb was in the tent. The gloom of evening was closing in on a desolate world. Overhead the sky was thick, and suddenly, with a great cry, Billy flung his arms straight up over his head and cursed that Law which could not be punished, the Law that had killed Scottie Deane. For he was that Law, and Isobel had called him a murderer. XVII ISOBEL FACES THE ABYSS It was not the face of MacVeigh-- the old MacVeigh-- that Rookie McTabb, the ex-constable, looked into a few moments later. Days of sickness could have laid no heavier hand upon him than had those few minutes in the darkened room of the cabin. His face was white and drawn. There were tense lines at the corners of his mouth and something strange and disquieting in his eyes. McTabb did not see the change until he came out into what remained of the day with little Isobel in his arms. Then he stared. "That blow got you bad," he said. "You look sick. Mebbe I'd better stay with you here to-night." "No, you hadn't," replied Billy, trying to throw off what he knew the other saw. "Take the kid over to the cabin. A night's sleep and I'll be as lively as a cat. I'm going to vaccinate her before you go." He went into the tent and dug out from his pack the small rubber pouch in which he carried a few medicines and a roll of medicated cotton. In a small bottle there were three vaccine points. He returned with these and the cotton.
