she took the medicine when very ill. If she used it oftener, its effect would disappear, and she would have nothing left to turn to at the worst.
"It was that bottle she was trying to find in the dark," Joan guessed. "She must have been too ill to try and light the gas. Now, how much was it that I saw her pour out? It might have been ten drops--no more."
So thinking, the girl filled a glass on the wash-handstand a third full of water, measured ten drops of the medicine with a steady hand, and raising Mrs. Gone's head, put the tumbler to her lips. The strong teeth seemed clenched, but some of the liquid must have passed their barrier, for the dark eyes opened wide and looked up into Joan's face.
"Too late----" the woman panted, with a gurgling in the throat which choked her words. "Dying--now. Wish that--you--you have been kind--only one in the world. My secret--you might have--Lord Northmuir would have given----"
The voice trailed away into silence. The gurgle died into a rattle; the woman's breast heaved and was still. Her eyes had not closed, but though they stared into Joan's, the spark of life behind their windows had gone out. Mrs. Gone was dead, and had taken her secret with her into the unknown.
Joan had never seen death before, but there was no mistaking it. Her first impulse was to run downstairs, call Miss Witt and a young doctor who had his office and bedroom on the dining-room floor. Nevertheless, when she had laid the heavy head gently down and sprung to her feet, she remained standing.
For some minutes she stood motionless, almost rigid, her lips pressed together, her eyes hard and bright. Then she struck one hand lightly upon the other, exclaiming half aloud: "I'll do it!"
It seemed certain by this time that no one had heard the crash of glass and the fall which had alarmed her, for the house was still. Nevertheless, Joan tiptoed to the door and bolted it. When she had done this, she opened all the drawers of the dressing-table and searched them carefully for papers. Discovering none, she left everything exactly as she had found it. Next she examined the pockets of the three or four dresses hanging in the wardrobe, but they were limp and empty. There were still left the leather portmanteau and handbag which had appealed to Miss Witt's respectful admiration. Both were locked, but Joan's instinct led her to look under the pillows on the bed, and there lay a key-ring. She was able to open portmanteau and bag, but not a paper of any kind was to be seen, and the girl recalled a remark of Miss Witt's, that never since Mrs. Gone had become a boarder in Woburn Place had she been known to receive or send a letter.
Having assured herself that no information was to be gained among the dead woman's possessions, Joan unlocked the door and went softly downstairs to rouse Miss Witt. She justified what she had done by reason of Mrs. Gone's last words, for she believed that the dead woman would have made her a present of the secret if she could.
Chapter VIII.
Lord Northmuir's Young Relative
Awakened and informed of what had happened, the housekeeper called the doctor, who looked at the body and certified that death had resulted from failure of the heart, which must have been long diseased. Joan paid for a good oak coffin and a decent funeral. She bought a grave at Kensal Green and ordered a neat stone to be erected. If she had previously earned Mrs. Gone's gratitude, she felt that she had now merited any reward which might accrue in future, and the curious, erasible tablet that did duty as her conscience was wiped clear.
The morning after Mrs. Gone's funeral, the girl put on her favourite frock of grey cloth, with a hat to match, which had been bought at one of the most fashionable shops in Monte Carlo. This costume, with grey gloves, grey shoes, and a grey chiffon parasol, ivory-handled, gave Joan an air of quiet smartness, a combination particularly appropriate for the adventure which she had planned. She hired a decorous brougham and said to the coachman: "Drive to Northmuir House, Belgrave Square."
It was but ten o'clock, and, as Joan had gleaned some information concerning the habits of the occupant, she was confident that he would be at home. Mrs. Gone had not been dead two hours when the girl began searching through her own scrapbook, compiled of cuttings taken from Society papers. Whenever she came across the description of any important member of the aristocracy--his or her home life, manners, fancies, and ways--she cut it out and pasted it into this book, in case it should become valuable for reference. The moment that the dying woman uttered the name of Northmuir, Joan's memory jumped to a paragraph (one of the first that had gone into the scrapbook), and as soon as she could shut herself up in the little back room, she had consulted her authority.
The Earl of Northmuir was, according to the paper from which the cutting had been clipped, still the handsomest man in England, though now long past middle age. Once he had been among the most popular also, but for some years he had lived more or less in retirement, owing to illness and family bereavements, seldom leaving his fine old town house in Belgrave Square.
"He'll be in London, and he won't be the sort of man to go out before noon," Joan said to herself.
Her heart was beating more quickly than usual, but her face was calm and untroubled, as she stood on the great porch at Northmuir House, asking a footman in sober livery if Lord Northmuir were at home.
The girl in the grey dress and grey hat, with large, soft ostrich feathers, might have been a young princess. Whatever she was, she merited civility, and the servant, who could not wholly conceal surprise, politely invited her to enter, while he inquired if his Lordship could receive a visitor. "What name shall I say?" he asked.
"Give him this, please," said Joan, handing the footman an envelope, addressed to "The Earl of Northmuir." Inside this envelope was a sheet of paper, blank, save for the words, "A messenger from Mrs. Gone, who is dead"; and the death notice was enclosed.
With this envelope the man went away, leaving her to wait in a large and splendid drawing-room, where stiffness of arrangement betrayed the absence of a woman's taste.
Joan looked about appreciatively, yet critically. Then, when she had gained an impressionist picture of the room, she glanced at the jewelled watch on her wrist, a present from Lady John Bevan after the sale of the Titania.
What if Lord Northmuir had never known the dead woman under the name of Gone? What if--there were many things which might go wrong, and Joan had put her whole stake on a single chance. If she had been mistaken--but as her mind played among surmises, the footman returned.
"His Lordship will see you in his study, if you will kindly come this way," the servant announced.
Joan rose with quiet dignity and followed the man along a pillared hall to a closed door. "The lady, my lord," murmured the footman, in opening it. Joan was left alone with a singularly handsome old man, who sat in a huge cushioned chair by the fireplace. It was summer still, but a fire of ship-logs sparkled with changing rainbow lights on the stone hearth. In a thin hand, Lord Northmuir held an exquisitely bound book. He must have been more than sixty, but his features were of the cameo--fine, classic cut, of which the beauty, like that of old marble, never dies, and it was easy to see why he had once borne a reputation as the handsomest man in England. It was easy to see also, by his eyes as they catalogued each item of Joan's beauty, that he had been a gallant man, not blind to the charms of women. Nevertheless, his voice was cold as he spoke to the unexpected visitor.
"I haven't the pleasure of knowing your name, or why you have honoured me by calling," he said. "Forgive my not rising. I am rather an invalid. Pray sit down. There is something I can do for you?"
"Several things, Lord Northmuir," returned the girl, taking the chair his gesture had indicated.
"You will tell me what they are?"
"I am anxious to tell you. In the first place, I wish to be a relation of yours, and not a poor relation. I wish to have a thousand pounds a year, either permanently or until my marriage, should I become the wife of a rich man through your introduction."
Lord Northmuir stared at the girl, and if there were not genuine astonishment in his eyes,
