"If I thought she had the slightest suspicion," declared her ladyship with a sudden hardness of her lips, "I'd--I'd close her mouth very quickly."

"And for ever, eh?" he asked meaningly.

"Yes, for ever."

"Bah!" he laughed. "You'd be afraid to do that, my dear Winnie," added the man, lowering his voice. "Your husband is blind, it's true; but there are other people in the world who are not. Recollect, Gabrielle is now nineteen, and she has her eyes open. She's the eyes and ears of Sir Henry. Not the slightest thing occurs in this household but it is told to him at once. His indifference to all is only a clever pretence."

"What!" she gasped quickly; "do you think he suspects?"

"Pray, what can he suspect?" asked the man very calmly, both hands in his trouser-pockets, as he leaned back against the table in front of her.

"He can only suspect things which his daughter knows," she said.

"But what does she know? What can she know?" he asked.

"How can we tell? I have watched, but can detect nothing. I am, however, suspicious, because she did not come to Connachan with us to-night."

"Why?"

"Walter Murie may know something, and may have told her."

"If so, then to close her lips would be useless. It would only bring a heavier responsibility upon us--and----" But he hesitated, without finishing his sentence. His meaning was apparent from the wry face she pulled at his remark. He did not tell her how he had, while she had been dancing and flirting that night, made his way back to the castle, or how he had compelled Gabrielle to go forth and speak with him. His action had been a bold one, yet its result had confirmed certain vague suspicions he had held.

Well he knew that the girl hated him heartily, and that she was in possession of a certain secret of his--one which might easily result in his downfall. He feared to tell the truth to this woman before him, for if he did so she would certainly withdraw from all a.s.sociation with him in order to save herself.

The key to the whole situation was held by that slim, sweet-faced girl, so devoted to her afflicted father. He was not quite certain as to the actual extent of her knowledge, and was as yet undecided as to what att.i.tude he should adopt towards her. He stood between the Baronet's wife and his daughter, and hesitated in which direction to follow.

What did she really know, he wondered. Had she overheard any of that serious conversation between Lady Heyburn and himself while they walked together in the glen on the previous evening? Such a _contretemps_ was surely impossible, for he remembered they had taken every precaution lest even Stewart, the head gamekeeper, might be about in order to stop trespa.s.sers, who, attracted by the beauties of Glencardine, tried to penetrate and explore them, and by so doing disturbed the game.

"And if the girl really knows?" he asked of the woman who stood there motionless, gazing out across the lawn fixedly towards the dawn.

"If she knows, James," she said in a hard, decisive tone, "then we must act together, quickly and fearlessly. We must carry out that--that plan you proposed a year ago!"

"You are quite fearless, then," he asked, looking straight into her fine eyes.

"Fearless? Of course I am," she answered unflinchingly. "We must get rid of her."

"Providing we can do so without any suspicion falling upon us."

"You seem to have become quite white-livered," she exclaimed to him with a harsh, derisive laugh. "You were not so a year ago--in the other affair."

His brows contracted as he reflected upon all it meant to him. The girl knew something; therefore, to seal her lips was imperative for their own safety. She was their enemy.

"You are mistaken," he answered in a low calm voice. "I am just as determined--just as fearless--as I was then."

"And you will do it?" she asked.

"If it is your wish," he replied simply.

"Good! Give me your hand. We are agreed. It shall be done."

And the man took the slim white hand the woman held out to him, and a moment later they ascended the great oak staircase to their respective rooms.

The pair were in accord. The future contained for Gabrielle Heyburn--asleep and all unconscious of the dastardly conspiracy--only that which must be hideous, tragic, fatal.

CHAPTER V

THE MURIES OF CONNACHAN

Elise, Lady Heyburn's French maid, discovered next morning that an antique snake-bracelet was missing, a loss which occasioned great consternation in the household.

Breakfast was late, and at table, when the loss was mentioned, Gabrielle offered to drive over to Connachan in the car and make inquiry and search. The general opinion was that it had been dropped in one of the rooms, and was probably still lying there undiscovered.

The girl's offer was accepted, and half an hour later the smaller of the two Glencardine cars--the "sixteen" Fiat--was brought round to the door by Stokes, the smart chauffeur. Young Gellatly, fresh down from Oxford, begged to be allowed to go with her, and his escort was accepted.

Then, in motor-cap and champagne-coloured dust-veil, Gabrielle mounted at the wheel, with the young fellow at her side and Stokes in the back, and drove away down the long avenue to the high-road.

The car was her delight. Never so happy was she as when, wrapped in her leather-lined motor-coat, she drove the "sixteen." The six-cylinder "sixty" was too powerful for her, but with the "sixteen" she ran half-over Scotland, and was quite a common object on the Perth to Stirling road. Possessed of nerve and full of self-confidence, she could negotiate traffic in Edinburgh or Glasgow, and on one occasion had driven her father the whole way from Glencardine up to London, a distance of four hundred and fifty miles. Her fingers pressed the b.u.t.ton of the electric horn as they descended the sharp incline to the lodge-gates; and, turning into the open road, she was soon speeding along through Auchterarder village, skirted Tullibardine Wood, down through Braco, and along by the Knaik Water and St. Patrick's Well into Glen Artney, pa.s.sing under the dark shadow of Dundurn, until there came into view the broad waters of Loch Earn.

The morning was bright and cloudless, and at such a pace they went that a perfect wall of dust stood behind them.

From the margin of the loch the ground rose for a couple of miles until it reached a plateau upon which stood the fine, imposing Priory, the ancestral seat of the Muries of Connachan. The aspect as they drove up was very imposing. The winding road was closely planted with trees for a large portion of its course, and the stately front of the western entrance, with its ma.s.sive stone portico and crenulated cornice, burst unexpectedly upon them.

From that point of view one seemed to have reached the gable-end of a princely edifice, crowned with Gothic belfries; yet on looking round it was seen that the approach by which the doorway had been reached was lined on one side with buildings hidden behind the cl.u.s.tering foliage; and through the archway on the left one caught a glimpse of the ivy-covered clock-tower and s.p.a.cious stable-yard and garage extending northwards for a considerable distance.

Gabrielle ran the car round to the south side of the house, where in the foreground were the well-kept parks of Connachan, the smooth-shaven lawn fringed with symmetrically planted trees, and the fertile fields extending away to the very brink of the loch.

The original fortalice of the Muries, half a mile distant, was, like Glencardine, a ruin. The present Priory, notwithstanding its old-fashioned towers and lancet windows, was a comparatively modern structure, and the ivy which partially covered some of the windows could claim no great antiquity; yet the general effect of the architectural grouping was most pleasing, and might well deceive the visitor or tourist into the supposition that it belonged to a very remote period.

It was, as a matter of fact, the work of Atkinson, who in the first years of the nineteenth century built Scone, Abbotsford, and Taymouth Castle.

With loud warning blasts upon the horn, Gabrielle Heyburn pulled up; but ere she could descend, Walter Murie, a good-looking, dark-haired young man in grey flannels, and hatless, was outside, hailing her with delight.

"Hallo, Gabrielle!" he cried cheerily, taking her hand, "what brings you over this morning, especially when we were told last night that you were so very ill?"

"The illness has pa.s.sed," exclaimed young Gellatly, shaking his friend's hand. "And we're now in search of a lost bracelet--one of Lady Heyburn's."

"Why, my mother was just going to wire! One of the maids found it in the boudoir this morning, but we didn't know to whom it belonged. Come inside. There are a lot of people staying over from last night." Then, turning to Gabrielle, he added, "By Jove! what dust there must be on the road! You're absolutely covered."

"Well," she laughed lightly, "it won't hurt me, I suppose. I'm not afraid of it."

Stokes took charge of the car and shut off the petrol, while the three went inside, pa.s.sing into a long, cool cloister, down which was arranged the splendid collection of antiques discovered or acquired by Malcolm Murie, the well-known antiquary, who had spent many years in Italy, and died in 1794. In cases ranged down each side of the long cloister, with its antique carved chairs, armour, and statuary, were rare Etruscan and Roman terra-cottas, one containing relics from the tomb of a warrior, which included a sword-hilt adorned with gold and a portion of a golden crown formed of lilies _in relievo_ of pure gold laid upon a mould of bronze; another case was full of bronze ornaments unearthed near Albano, and still another contained rare Abyssinian curios. The collection was renowned among antiquaries, and was often visited by Sir Henry, who would be brought there in the car by Gabrielle, and spend hours alone fingering the objects in the various cases.

Sir George Murie and Sir Henry Heyburn were close friends; therefore it was but natural that Walter, the heir to the Connachan estate, and Gabrielle should often be thrown into each other's company, or perhaps that the young man--who for the past twelve months had been absent on a tour round the world--should have loved her ever since the days when she wore short skirts and her hair down her back. He had been sorely puzzled why she had not at the last moment come to the ball. She had promised that she would be with them, and yet she had made the rather lame excuse of a headache.

Truth to tell, Walter Murie had during the past week been greatly puzzled at her demeanour of indifference. Seven days ago he had arrived in London from New York, but found no letter from her awaiting him at the club, as he had expected. The last he had received in Detroit a month before, and it was strangely cold, and quite unusual. Two days ago he had arrived home, and in secret she had met him down at the end of the glen at Glencardine. At her wish, their first meeting had been clandestine. Why?
