Freed from the nightmare of doubt, with a cry she ran forward. She saw Peabody, his back against a wall, a levelled automatic in his hand; her brother at the entrance to a tunnel like the one from which she had just appeared. His arms were raised above his head. At his feet lay a revolver. For an instant, with disbelief, he stared at Monica, and then, as though assured that it was she, his eyes dilated. In them were fear and horror.
