A slight mist had fallen, and fields and lanes were gradually enveloping themselves in a gray shroud which rose in thick vapour from the river. Also it was getting dark, yet to Cleek, whose whole heart and soul were bound up in the neighbourhood that formed the temporary home of Ailsa Lorne, the one woman in the world for him, the way was as clear as though he held a map in his hand, and a torch whereby to see it with.

He knew that the dark, tree-lined lane ran on for some thousand yards, with but two curves, until it reached the neighbouring parish where it divided in a fork. Here one road led to the gateways of Cheyne Court and to the river-bank. The other proceeded to the rear of the village of Hampton. On the other side, draggled trees and matted gorse bushes were scattered over a piece of land which was used largely for the encampment of tribes of wandering gipsies, travelling booths, and circuses. It was as well the chosen pitch of the annual fair, an occasion that brought the rag-tail and riff-raff of London to over-flow the tiny hamlet, and give the inhabitants food for gossip for the remainder of the year.

Past these the limousine whizzed on like a thing possessed, taking the last mile between the forked lane to the house at such a speed that it would have overtaken or passed any other vehicle that might have been coming to the hall. But the lane was deserted and they passed down it alone. Another quarter of an hour took them past a big house standing half hidden in its own grounds. This was, as Cleek knew, the home of Lady Brenton, whom Ailsa had mentioned but a short time ago as being a neighbour of both Miss Cheyne and herself.

Some five hundred feet more, and they came to a pair of very dilapidated iron gates, standing wide open, and covered with a heavy coating of orange rust. Creepers twisted and twined themselves about the rotting rungs, clothing them with a sombre dignity that shrouded much of their evident neglect.

Cleek drove up the grass-grown strip of pebbles that was the pathway into a tangled avenue of overhanging trees that looked grim and forbidding. It was no wonder that few travellers passing that way guessed the existence of a house behind them.

As for that house itself, to Cleek's eyes it showed neither light nor signs of habitation. No smoke issued from its chimney-pots, nor was there a sound. To all intents and purposes, it might have been an empty building, and Cleek, who had hopped off the driver's seat, dived hastily for his powerful electric torch, preparatory to making a closer investigation.

The mist which had been gradually rising now seemed to wrap them in an impenetrable veil. The moon's light had vanished and for a moment only the drip-drip of some distant water broke on his ears as he stood alert, watchful, and keen. And even as he stood came a sound that froze his heart's blood, a sound terrifying in the broad open glory of daylight, but here, in the dark and chill, muffled by distance, yet none the less unmistakable, a very terror indeed. And that sound was the sharp crack of a revolver!

For a moment, as its full significance was borne in on his mind, Cleek stood rigid. Then as the door of the car flew open he turned to meet Lady Margaret in the very act of jumping out.

His first thought was as to whether she, too, had heard the ill-omened sound, but it was evident that she had not realized, or perhaps even noticed it. A frown furrowed her clear, child's brow and she clapped her hands together with a little gesture of impatience.

"Oh, can't you make any one hear, Mr. Deland?" she cried despairingly. "Please do make them hurry. I am so tired."

Cleek started forward, and dashing up the two or three stone steps, sent peal after peal of the jangling, old-fashioned bell reverberating through the house. There came no answer.

He bent down and peered through the letter-box, at the same time striking a match and letting its feeble light struggle through the aperture. All within was dark, and yet Cleek's tense nerves gave a little quivery jump. For a sound, slight though it was, came to his trained ears. It was the sound of a padded footstep, and to his nostrils was borne a strange, sweet scent, familiar yet tantalizingly unknown.

Again and again he rang the bell, and the echoes, pealing through the silent house, came back to him maddeningly. At last Lady Margaret, who had come up to him, laid a hand upon his shoulder and peered for a moment up into his face.

"I know how to get in," she said. "Let us try that window. It is the dining room, and should be quite easy to manage. Please try and force it for me, will you?"

Speaking, she ran lightly along the stone terrace and pulled feebly at the window, which was evidently locked. Cleek, following closely on her heels, felt a thrill of something akin to fear because of what that single shot might mean.

"Come," he said, suddenly switching round upon his heel. "Let's give the task up for to-night, Lady Margaret. There is nothing to be gained here, and Miss Lorne will be able to put you up comfortably until morning comes. Let's get away from here, I beg."

She looked at him in wide-eyed surprise at the suggestion.

"No, no, please. I would rather stay now I am here. Besides, it is my home, and Aunt Marion will be expecting me."

A few swift touches of his knife, and the antiquated lock gave way. With a little sigh of relief she scrambled through the window and entered the room with the air of one who has arrived home at last, and stood a moment looking quickly about her. Cleek followed closely upon her heels, his heart pumping furiously and his blood "up" for anything that might ensue.

The interior of the room was very dark, but apparently the girl knew her way, for she plunged forward unhesitatingly, only turning to speak to Cleek who hesitated in the background.

"Strike a match, please, Mr. Deland," she commanded with a little imperious gesture. "There's a lamp over here." Cleek, following the direction of her hand, speedily espied one which was standing upon an adjacent table.

With its friendly aid he was able to note the worn and threadbare appearance of everything, blurred and shadowy though it was. The only striking object was placed in the centre of a small stand and it was the picture of the girl he had helped to bring to her natural home. He turned instinctively as though to compare the likeness and saw that she had thrown aside her hat and coat and sunk down in the old leather chair, her blue eyes looking piteously at him as he came toward her.

"That's right," he said with a quick smile. "If you will rest here, Lady Margaret, I will go on a voyage of discovery, and see what has become of the servants. Your aunt has probably gone to meet you. I shall not be long and I will light this other lamp for you so that you won't be quite so shadowy. There, that's better. Don't be afraid, Lady Margaret." With a friendly little nod of encouragement he disappeared through the door and came out into a network of passages which were all wainscoted, while the floors were covered with dust, as if they had been unswept for months. From room to room he went. Each one was more lonely, dark, and deserted than the last, yet over all there hung an indefinable dread that made Cleek, hardy of courage as he was, wish that his faithful henchman Dollops, or his friend and ally Superintendent Narkom, were within reach. The last room of all at the end of a passage proved to be a small ballroom, a low-ceilinged spot littered with dust, its corners thick with cobwebs. An odd chair or so stood against the wall, leaving the wax-polished parquetted floor strangely bare. But it was not this that struck Cleek. It was a sight in the far corner that caused him to stop suddenly and suck in his breath, while the torch in his firm fingers trembled as though for a moment the grip was relaxed.

For there, lying crumpled up in a lax, horrible heap, lay the figure of a woman! Cleek's torch shed a disk of light upon the upturned face and he sucked in his breath again, for the features were distorted and appalling, and death marked them with his unmistakable trace.

For an instant Cleek hesitated, and his mind went back to that pistol shot such a short time ago. This poor huddled Thing with its staring eyes and gaping, twisted mouth was the answer to it. He walked rapidly toward the body and saw that it was of an old woman of about seventy but who had evidently kept up the fiction of youth as long as she could, for her cheeks were heavy with rouge, her hair was obviously dyed to a bright golden colour and her rich silk dress in the most juvenile of fashions. As he noted the flashing rings on her fingers and the priceless lace at her wrists, Cleek began to understand a few things, and among them the reason why Lady Margaret had arrived in England to find no one waiting to welcome her at the station.

For here, without a doubt, was the Honourable Miss Cheyne. Who had murdered her, and for what reason, remained to be discovered. Robbery was out of the question, for many hundreds of pounds worth of jewellery was there on her hands in the shape of rings and bracelets. Revenge? For what? By whom?

Silently Cleek stood looking down on the body, his chin held between his thumb and forefinger, his brows furrowed. Here was a riddle indeed. For one moment he stood stock-still, then with a sudden bound leaped over to the window, which stood bare and curtainless, looked out on to the grounds, and stood listening. For a sound, slight but none the less distinct, the tiny cracking of a twig, had arrested his attention. What he saw made his heart and pulses hammer furiously. For a moment the impenetrable curtain of mist had lifted and the struggling moonbeams flung a shadowy path of light across the lawn over which moved the figure of a woman clad in white, clinging robes, her head swathed in a white turban. A woman, at such a time, in this place! The thing was so startling that Cleek's brain reeled. Involuntarily he made a movement as if to follow her, but even as he did so the figure turned, and Cleek's amazement deepened still further as he caught a glimpse of a dark face and what might have been a dark beard. The curtain of mist had descended again, and the scene was blotted out before its full significance had been realized.

A woman and at such an hour in such a place! At any other time, under any other circumstances, Cleek might have thought it one of the maids speeding away to a meeting with some yokel lover, but under these circumstances, when there was no evidence of a servant's care in the place, such an hypothesis was out of the question. Yet he was loath to believe a woman's hand could have committed such ruthless murder. He switched round now in sudden fear. At any moment Lady Margaret might be tired of waiting and follow on his track. At all costs she must be prevented from doing that, for the shock would surely prove beyond her strength.

He crossed the room, and groped his way into the passage again. There was no key in the door, so it was impossible to lock away the secret of the ballroom, but he piled up two or three chairs in order to minimize the risk.

Hurriedly he traversed the corridors which lay between the back of the house and the dining room where he had left Lady Margaret. Pushing open the door cautiously, he entered. To his unspeakable relief the girl had curled herself up in the big arm-chair and gone to sleep. A swift glance showed him that it would be useless to awaken her; she was plainly exhausted by the events of the day, and she would sleep like this for hours. Though greatly disliking the idea, Cleek could think of nothing better than to make for the village, arouse the police, and take Lady Margaret down to Miss Lorne's cottage.

Treading as lightly as a cat, Cleek tiptoed back into the hall, locked the door softly behind him, and sped away.

He meant to pass Ailsa's cottage without breaking the journey, for he dreaded telling her to what a tragedy they had brought their young charge, but at the little gate a slender figure awaited him. Cleek halted almost mechanically.

"I didn't mean to wait up a minute, for I am so tired myself," said Ailsa, "but you see, I wanted to learn whether the old lady was very angry."

She looked up into Cleek's sombre face, and was struck by its pallor. "Why, is there anything wrong?" she said quickly. "You look pale, dear, and upset. Tell me."

"Yes, very wrong indeed, Ailsa mine," responded Cleek grimly. "Miss Cheyne has been murdered, and I am driving down to rouse the police."

A cry of horror broke from Ailsa's parted lips. She caught Cleek's arm in her two hands, and her eyes sought his face. "Lady Margaret—is she in the limousine with you?" she asked anxiously.

Cleek twitched back his shoulders and shook his head.

"No, dear. She is sound asleep in the dining room; locked in. I did not want to rouse her until I had got the police in charge. When I have I will bring her back to you."

"Let me come with you," said Ailsa swiftly.

But this Cleek would not allow, for the tongues of village gossips are bitter things to fight.

"No, dear, I cannot permit that," he responded, looking down into her soft, misty eyes. "You understand, of course. And the child is perfectly safe, and will not wake for some time. Time enough for your charitable instincts to awaken when I bring her back to you. Now I must go."
