"It is wonderful what love will sometimes do," she spoke softly. "In the last few hours Marie has bared her soul to me, John. What she has been she has not tried to hide from me, nor even from the man she loves. She was one of Mortimer FitzHugh's tools. DeBar saw her and loved her, and she sold herself to him in exchange for the secret of the gold. When they came into the North the wonderful thing happened. She loved DeBar—not in the way of her kind, but as a woman in whom had been born a new heart and a new soul and a new joy. She defied FitzHugh; she told DeBar how she had tricked him.

"This morning FitzHugh attempted his old familiarity with her, and DeBar struck him down. The act gave them excuse for what they had planned to do. Before her eyes Marie thought they had killed the man she loved. She flung herself on his breast, and she said she could not feel his heart beat, and his blood flowed warm against her hands and face. Both she and DeBar had determined to warn us if they could. Only a few minutes before DeBar was stabbed he had let off his rifle—an accident, he said. But it was not an accident. It was the shot Donald heard in the cavern. It saved us, John! And Marie, waiting her opportunity, fled to us in the plain. DeBar was not killed. He says my screams brought him back to life. He came out—and killed Quade with a knife. Then he fell at our feet. A few minutes later Donald came. DeBar is in another cabin. He is not fatally hurt, and Marie is happy."

She was stroking his hand when she finished. The curious rumbling came softly in MacDonald's beard and his eyes were bright with a whimsical humour.

"I pretty near bored a hole through poor Joe when I come up," he chuckled. "But you bet I hugged him when I found what he'd done, Johnny! Joe says their camp was just over the range from us that night FitzHugh looked us up, an' Joanne thought she'd been dreamin'. He didn't have any help, but his intention was to finish us alone—murder us asleep—when Joanne cried out. Joe says it was just a devil's freak that took 'im to the top of the mountain alone that night. He saw our fire an' came down to investigate."

A low voice was calling outside the door. It was Marie. As Joanne went to her a quick gleam came into old Donald's eyes. He looked behind him cautiously to see that she had disappeared, then he bent over Aldous, and whispered hoarsely:

"Johnny, I had a most cur'ous word with Rann—or FitzHugh—afore he died! He wasn't dead when I went to him. But he knew he was dyin'; an' Johnny, he was smilin' an' cool to the end. I wanted to ask 'im a question, Johnny. I was dead cur'ous to know why the grave were empty! But he asked for Joanne, an' I couldn't break in on his last breath. I brought her. The first thing he asked her was how people had took it when they found out he'd poisoned his father! When Joanne told him no one had ever thought he'd killed his father, FitzHugh sat leanin' against the saddles for a minit so white an' still I thought he 'ad died with his eyes open. Then it came out, Johnny. He was smilin' as he told it. He killed his father with poison to get his money. Later he came to America. He didn't have time to tell us how he come to think they'd discovered his crime. He was dyin' as he talked. It came out sort o' slobberingly, Johnny. He thought they'd found 'im out. He changed his name, an' sent out the report that Mortimer FitzHugh had died in the mount'ins. But Johnny, he died afore I could ask him about the grave!"

There was a final note of disappointment in old Donald's voice that was almost pathetic.

"It was such a cur'ous grave," he said. "An' the clothes were laid out so prim an' nice."

Aldous laid his hand on MacDonald's.

"It's easy, Mac," he said, and he wanted to laugh at the disappointment that was still in the other's face. "Don't you see? He never expected any one to dig into the grave. And he put the clothes and the watch and the ring in there to get rid of them. They might have revealed his identity. Why, Donald——"
