He shuddered frightfully, then staggered across the floor.

Motion removed the numbness from his mind. The first paralysing wave of terror had passed, so now he saw again clearly. He looked upon his wife, with hatred growing in her eyes; he thought of the possible foes already in wait outside the door; he beheld the window, and knew that salvation lay there.

Thither he went, with an attempt at a smile upon his features. Ah, there was shelter and life in that dark night. But then the lightning burst forth wildly, converting the outer blackness into a weird atmosphere of shuddering blue.

He fell back with a shout no effort could repress. In the brief space of light had been plainly visible a knot of men crossing the prairie in that direction.

But his wife had seen them, too. The dreadful truth, so far a suspicion, now became a certainty. Unwittingly she had taken to husband the vilest and most cowardly of all her country's treacherous sons.

'I see,' she said, bending forward like the snake about to strike. 'You are afraid of these men. They are coming here. Perhaps you know why.'

One minute of perfect coolness, and he would be safe. He could escape by the door, pass out at the back, reach open prairie, then make for the bush. None could touch him there. But he must first secure his weapons, which lay in the next room.

So he laughed feebly, and smiled in ghastly fashion upon his wife. 'It's all right, Marie, chérie. The heat has knocked me over altogether. I'm just going out for a bit.'

But as he crossed the floor, she stepped forward and put herself in his way.

'Where are you going?'
