The bungalow was darkened by drawn curtains when he entered. One after another he let them up, and the sun poured in. Brady had left his place in order, and Keith felt about him an atmosphere of cheer that was a mighty urge to his flagging spirits. Brady was a home man without a wife. The Company's agent had called his place "The Shack" because it was built entirely of logs, and a woman could not have made it more comfortable. Keith stood in the big living-room. At one end was a strong fireplace in which kindlings and birch were already laid, waiting the touch of a match. Brady's reading table and his easy chair were drawn up close; his lounging moccasins were on a footstool; pipes, tobacco, books and magazines littered the table; and out of this cheering disorder rose triumphantly the amber shoulder of a half-filled bottle of Old Rye.

Keith found himself chuckling. His grin met the lifeless stare of a pair of gla.s.s eyes in the huge head of an old bull moose over the mantel, and after that his gaze rambled over the walls ornamented with mounted heads, pictures, snowshoes, gun-racks and the things which went to make up the comradeship and business of Brady's picturesque life.

Keith could look through into the little dining-room, and beyond that was the kitchen. He made an inventory of both and found that McDowell was right. There were nutcrackers in Brady's establishment. And he found the bathroom. It was not much larger than a piano box, but the tub was man's size, and Keith raised a window and poked his head out to find that it was connected with a rainwater tank built by a genius, just high enough to give weight sufficient for a water system and low enough to gather the rain as it fell from the eaves. He laughed outright, the sort of laugh that comes out of a man's soul not when he is amused but when he is pleased. By the time he had investigated the two bedrooms, he felt a real affection for Brady. He selected the agent's room for his own. Here, too, were pipes and tobacco and books and magazines, and a reading lamp on a table close to the bedside. Not until he had made a closer inspection of the living-room did he discover that the Shack also had a telephone.

By that time he noted that the sun had gone out. Driving up from the west was a ma.s.s of storm clouds. He unlocked a door from which he could look up the river, and the wind that was riding softly in advance of the storm ruffled his hair and cooled his face. In it he caught again the old fancy--the smells of the vast reaches of unpeopled prairie beyond the rim of the forest, and the luring chill of the distant mountain tops. Always storm that came down with the river brought to him voice from the river's end. It came to him from the great mountains that were a pa.s.sion with him; it seemed to thunder to him the old stories of the mightiest fastnesses of the Rockies and stirred in him the child-bred yearning to follow up his beloved river until he came at last to the mystery of its birthplace in the cradle of the western ranges. And now, as he faced the storm, the grip of that desire held him like a strong hand.

The sky blackened swiftly, and with the rumbling of far-away thunder he saw the lightning slitting the dark heaven like bayonets, and the fire of the electrical charges galloped to him and filled his veins. His heart all at once cried out words that his lips did not utter. Why should he not answer the call that had come to him through all the years? Now was the time--and why should he not go? Why tempt fate in the hazard of a great adventure where home and friends and even hope were dead to him, when off there beyond the storm was the place of his dreams? He threw out his arms. His voice broke at last in a cry of strange ecstasy. Not everything was gone! Not everything was dead! Over the graveyard of his past there was sweeping a mighty force that called him, something that was no longer merely an urge and a demand but a thing that was irresistible. He would go! Tomorrow--today--tonight--he would begin making plans!

He watched the deluge as it came on with a roar of wind, a beating, hissing wall under which the tree tops down in the edge of the plain bent their heads like a mult.i.tude of people in prayer. He saw it sweeping up the slope in a ma.s.s of gray dragoons. It caught him before he had closed the door, and his face dripped with wet as he forced the last inch of it against the wind with his shoulder. It was the sort of storm Keith liked. The thunder was the rumble of a million giant cartwheels rolling overhead.

Inside the bungalow it was growing dark as though evening had come. He dropped on his knees before the pile of dry fuel in the fireplace and struck a match. For a s.p.a.ce the blaze smoldered; then the birch fired up like oil-soaked tinder, and a yellow flame crackled and roared up the flue. Keith was sensitive in the matter of smoking other people's pipes, so he drew out his own and filled it with Brady's tobacco. It was an English mixture, rich and aromatic, and as the fire burned brighter and the scent of the tobacco filled the room, he dropped into Brady's big lounging chair and stretched out his legs with a deep breath of satisfaction. His thoughts wandered to the clash of the storm. He would have a place like this out there in the mystery of the trackless mountains, where the Saskatchewan was born. He would build it like Brady's place, even to the rain-water tank midway between the roof and the ground. And after a few years no one would remember that a man named John Keith had ever lived.

Something brought him suddenly to his feet. It was the ringing of the telephone. After four years the sound was one that roused with an uncomfortable jump every nerve in his body. Probably it was McDowell calling up about the j.a.p or to ask how he liked the place. Probably--it was that. He repeated the thought aloud as he laid his pipe on the table. And yet as his hand came in contact with the telephone, he felt an inclination to draw back. A subtle voice whispered him not to answer, to leave while the storm was dark, to go back into the wilderness, to fight his way to the western mountains.

With a jerk he unhooked the receiver and put it to his ear.

It was not McDowell who answered him. It was not Shan Tung. To his amazement, coming to him through the tumult of the storm, he recognized the voice of Miriam Kirkstone!

VII

Why should Miriam Kirkstone call him up in an hour when the sky was livid with the flash of lightning and the earth trembled with the roll of thunder? This was the question that filled Keith's mind as he listened to the voice at the other end of the wire. It was pitched to a high treble as if unconsciously the speaker feared that the storm might break in upon her words. She was telling him that she had telephoned McDowell but had been too late to catch him before he left for Brady's bungalow; she was asking him to pardon her for intruding upon his time so soon after his return, but she was sure that he would understand her. She wanted him to come up to see her that evening at eight o'clock. It was important--to her. Would he come?

Before Keith had taken a moment to consult with himself he had replied that he would. He heard her "thank you," her "good-by," and hung up the receiver, stunned. So far as he could remember, he had spoken no more than seven words. The beautiful young woman up at the Kirkstone mansion had clearly betrayed her fear of the lightning by winding up her business with him at the earliest possible moment. Why, then, had she not waited until the storm was over?

A pounding at the door interrupted his thought. He went to it and admitted an individual who, in spite of his water-soaked condition, was smiling all over. It was Wallie, the j.a.p. He was no larger than a boy of sixteen, and from eyes, ears, nose, and hair he was dripping streams, while his coat bulged with packages which he had struggled to protect, from the torrent through which he had forced his way up the hill. Keith liked him on the instant. He found himself powerless to resist the infection of Wallie's grin, and as Wallie hustled into the kitchen like a wet spaniel, he followed and helped him unload. By the time the little j.a.p had disgorged his last package, he had a.s.sured Keith that the rain was nice, that his name was Wallie, that he expected five dollars a week and could cook "like heaven." Keith laughed outright, and Wallie was so delighted with the general outlook that he fairly kicked his heels together. Thereafter for an hour or so he was left alone in possession of the kitchen, and shortly Keith began to hear certain sounds and catch occasional odoriferous whiffs which a.s.sured him that Wallie was losing no time in demonstrating his divine efficiency in the matter of cooking.

Wallie's coming gave him an excuse to call up McDowell. He confessed to a disquieting desire to hear the inspector's voice again. In the back of his head was the fear of Shan Tung, and the hope that McDowell might throw some light on Miriam Kirkstone's unusual request to see her that night. The storm had settled down into a steady drizzle when he got in touch with him, and he was relieved to find there was no change in the friendliness of the voice that came over the telephone. If Shan Tung had a suspicion, he had kept it to himself.

To Keith's surprise it was McDowell who spoke first of Miss Kirkstone.

"She seemed unusually anxious to get in touch with you," he said. "I am frankly disturbed over a certain matter, Conniston, and I should like to talk with you before you go up tonight."

Keith sniffed the air. "Wallie is going to ring the dinner bell within half an hour. Why not slip on a raincoat and join me up here? I think it's going to be pretty good."

"I'll come," said McDowell. "Expect me any moment."

Fifteen minutes later Keith was helping him off with his wet slicker.

He had expected McDowell to make some observation on the cheerfulness of the birch fire and the agreeable aromas that were leaking from Wallie's kitchen, but the inspector disappointed him. He stood for a few moments with his back to the fire, thumbing down the tobacco in his pipe, and he made no effort to conceal the fact that there was something in his mind more important than dinner and the cheer of a grate.

His eyes fell on the telephone, and he nodded toward it. "Seemed very anxious to see you, didn't she, Conniston? I mean Miss Kirkstone."

"Rather."

McDowell seated himself and lighted a match. "Seemed--a little--nervous--perhaps," he suggested between puffs. "As though something had happened--or was going to happen. Don't mind my questioning you, do you, Derry?"

"Not a bit," said Keith. "You see, I thought perhaps you might explain--"

There was a disquieting gleam in McDowell's eyes. "It was odd that she should call you up so soon--and in the storm--wasn't it? She expected to find you at my office. I could fairly hear the lightning hissing along the wires. She must have been under some unusual impulse."

"Perhaps."

McDowell was silent for a s.p.a.ce, looking steadily at Keith, as if measuring him up to something.

"I don't mind telling you that I am very deeply interested in Miss Kirkstone," he said. "You didn't see her when the Judge was killed. She was away at school, and you were on John Keith's trail when she returned. I have never been much of a woman's man, Conniston, but I tell you frankly that up until six or eight months ago Miriam was one of the most beautiful girls I have ever seen. I would give a good deal to know the exact hour and date when the change in her began. I might be able to trace some event to that date. It was six months ago that she began to take an interest in the fate of John Keith. Since then the change in her has alarmed me, Conniston. I don't understand. She has betrayed nothing. But I have seen her dying by inches under my eyes.

She is only a pale and drooping flower compared with what she was. I am positive it is not a sickness--unless it is mental. I have a suspicion.

It is almost too terrible to put into words. You will be going up there tonight--you will be alone with her, will talk with her, may learn a great deal if you understand what it is that is eating like a canker in my mind. Will you help me to discover her secret?" He leaned toward Keith. He was no longer the man of iron. There was something intensely human in his face.

"There is no other man on earth I would confide this matter to," he went on slowly. "It will take--a gentleman--to handle it, someone who is big enough to forget if my suspicion is untrue, and who will understand fully what sacrilege means should it prove true. It is extremely delicate. I hesitate. And yet--I am waiting, Conniston. Is it necessary to ask you to pledge secrecy in the matter?"

Keith held out a hand. McDowell gripped it tight.

"It is--Shan Tung," he said, a peculiar hiss in his voice. "Shan Tung--and Miriam Kirkstone! Do you understand, Conniston? Does the horror of it get hold of you? Can you make yourself believe that it is possible? Am I mad to allow such a suspicion to creep into my brain?

Shan Tung--Miriam Kirkstone! And she sees herself standing now at the very edge of the pit of h.e.l.l, and it is killing her."

Keith felt his blood running cold as he saw in the inspector's face the thing which he did not put more plainly in word. He was shocked. He drew his hand from McDowell's grip almost fiercely.

"Impossible!" he cried. "Yes, you are mad. Such a thing would be inconceivable!"

"And yet I have told myself that it is possible," said McDowell. His face was returning into its iron-like mask. His two hands gripped the arms of his chair, and he stared at Keith again as if he were looking through him at something else, and to that something else he seemed to speak, slowly, weighing and measuring each word before it pa.s.sed his lips. "I am not superst.i.tious. It has always been a law with me to have conviction forced upon me. I do not believe unusual things until investigation proves them. I am making an exception in the case of Shan Tung. I have never regarded him as a man, like you and me, but as a sort of superphysical human machine possessed of a certain psychological power that is at times almost deadly. Do you begin to understand me? I believe that he has exerted the whole force of that influence upon Miriam Kirkstone--and she has surrendered to it. I believe--and yet I am not positive."

"And you have watched them for six months?"

"No. The suspicion came less than a month ago. No one that I know has ever had the opportunity of looking into Shan Tung's private life. The quarters behind his cafe are a mystery. I suppose they can be entered from the cafe and also from a little stairway at the rear. One night--very late--I saw Miriam Kirkstone come down that stairway. Twice in the last month she has visited Shan Tung at a late hour. Twice that I know of, you understand. And that is not all--quite."

Keith saw the distended veins in McDowell's clenched hands, and he knew that he was speaking under a tremendous strain.

"I watched the Kirkstone home--personally. Three times in that same month Shan Tung visited her there. The third time I entered boldly with a fraud message for the girl. I remained with her for an hour. In that time I saw nothing and heard nothing of Shan Tung. He was hiding--or got out as I came in."

Keith was visioning Miriam Kirkstone as he had seen her in the inspector's office. He recalled vividly the slim, golden beauty of her, the wonderful gray of her eyes, and the shimmer of her hair as she stood in the light of the window--and then he saw Shan Tung, effeminate, with his sly, creeping hands and his narrowed eyes, and the thing which McDowell had suggested rose up before him a monstrous impossibility.

"Why don't you demand an explanation of Miss Kirkstone?" he asked.

"I have, and she denies it all absolutely, except that Shan Tung came to her house once to see her brother. She says that she was never on the little stairway back of Shan Tung's place."

"And you do not believe her?"

"a.s.suredly not. I saw her. To speak the cold truth, Conniston, she is lying magnificently to cover up something which she does not want any other person on earth to know."

Keith leaned forward suddenly. "And why is it that John Keith, dead and buried, should have anything to do with this?" he demanded. "Why did this 'intense interest' you speak of in John Keith begin at about the same time your suspicions began to include Shan Tung?"

McDowell shook his head. "It may be that her interest was not so much in John Keith as in you, Conniston. That is for you to discover--tonight. It is an interesting situation. It has tragic possibilities. The instant you substantiate my suspicions we'll deal directly with Shan Tung. Just now--there's Wallie behind you grinning like a Cheshire cat. His dinner must be a success."

The diminutive j.a.p had noiselessly opened the door of the little dining-room in which the table was set for two.

Keith smiled as he sat down opposite the man who would have sent him to the executioner had he known the truth. After all, it was but a step from comedy to tragedy. And just now he was conscious of a bit of grisly humor in the situation.
