“Yes, why did it?” gasped Linda. “Donald, I must leave you a minute. I’ve got to know if I saw a head peer over just as that stone came down.”

“Be careful what you do!” he cried after her.

Linda sprang to her feet and rushed to the car. She caught out the field glasses and threw the strap over her head as she raced to the far side of the fireplace where the walls were not so sheer. Katherine O’Donovan promptly seized the axe, caught its carrying strap lying beside it, thrust the handle through, swung it over her own head, dropped it between her shoulders, and ripping off her dress skirt she started up the cliff after Linda. Linda was climbing so swiftly and so absorbedly that she reached the top before she heard a sound behind her. Then she turned with a white face, and her mouth dropped open as she saw Katy three fourths of the way up the cliff. For one second she was again stiff with terror, then, feeling she could do nothing, she stepped back out of sight and waited a second until Katy’s red head and redder face appeared over the edge. Realizing that her authority was of no avail, that Katy would follow her no matter where she went or what she did, and with no time to argue, Linda simply called to her encouragingly: “Follow where I go; take your time; hang tight, old dear, it’s dangerous!”

She started around the side of the mountain, heading almost straight upward, traveling as swiftly and as noiselessly as possible. Over big boulders, on precarious footing, clinging to bushes, they made their way until they reached a place that seemed to be sheer above them; certainly it was for hundreds of feet below. On a point of rock screened by overhanging bushes Linda paused until Katy overtook her.

“We are about stalled,” she panted. “Find a good footing and stay where you are. I’m going to climb out on these bushes and see if I can get a view of the mountain side.”

Advancing a few yards, Linda braced herself, drew around her glasses, and began searching the side of the mountain opposite her and below as far as she could range with the glasses. At last she gave up.

“Must have gone the other way,” she said to Katy. “I’ll crawl back to you. We’ll go after help and get Donald out. There will be time enough to examine the cliff afterward; but I am just as sure now as I will be when it is examined that that stone was purposely loosened to a degree where a slight push would drop it. As Donald says, there’s no reason why it should hang there for centuries and fall on him to-day. Shut your eyes, old dear, and back up. We must go to Donald. I rather think it’s on one of his feet from what he said. Let me take one more good look.”

At that minute from high on the mountain above them a shower of sand and pebbles came rattling down. Linda gave Katy one terrified look.

“My God!” she panted. “He’s coming down right above us!”

Just how Linda recrossed the bushes and reached Katy she did not know. She motioned for her to make her way back as they had come. Katy planted her feet squarely upon the rock. Her lower jaw shot out; her eyes were aflame. She stood perfectly still with the exception of motioning Linda to crowd back under the bushes, and again Linda realized that she had no authority; as she had done from childhood when Katy was in earnest, Linda obeyed her. She had barely reached the overhanging bushes, crouched under them, and straightened herself, when a small avalanche came showering down, and a minute later a pair of feet were level with her head. Then screened by the bushes, she could have reached out and touched Oka Sayye. As his feet found a solid resting place on the ledge on which Linda and Katy stood, and while he was still clinging to the bushes, Katherine O’Donovan advanced upon him. He had felt that his feet were firm, let go his hold, and turned, when he faced the infuriated Irishwoman. She had pulled the strap from around her neck, slipped the axe from it, and with a strong thrust she planted the head of it against Oka Sayye’s chest so hard that she almost fell forward. The Jap plunged backward among the bushes, the roots of which had supported Linda while she used the glasses. Then he fell, sliding among them, snatching wildly. Linda gripped the overhanging growth behind which she had been screened, and leaned forward.
