CHAPTER XXIII.

PIANO PRACTICE.

CAFFYN was conscious of a certain excitement that Sunday evening as he waited for Mark Ashburn's arrival. He felt that he might be standing on the threshold of a chamber containing the secret of the other's life—the key of which that very evening might deliver into his hands. He was too cautious to jump at hasty conclusions; he wished before deciding upon any plan of action to be practically certain of his facts; a little skilful manipulation, however, would most probably settle the question one way or the other, and if the result verified his suspicions he thought he would know how to make use of his advantage. There is a passage in the 'Autocrat of the Breakfast Table' where the author, in talking of the key to the side-door by which every person's feelings may be entered, goes on to say, 'If nature or accident has put one of these keys into the hands of a person who has the torturing instinct, I can only solemnly pronounce the words that justice utters over its doomed victims, "The Lord have mercy on your soul!"' There, it is true, the key in question unlocks the delicate instrument of the nervous system, and not necessarily a Bluebeard's chamber of guilt; but where the latter is also the case to some extent the remark by no means loses in significance, and if any man had the torturing instinct to perfection, Caffyn might be said to be that individual. There was nothing he would enjoy more than practising upon a human piano and putting it hopelessly out of tune; but pleasant as this was, he felt he might have to exercise some self-denial here, at all events for the present, lest his instrument should become restive and escape before he had quite made up his mind what air he could best play upon it.

In the meantime Mark was preparing to keep the appointment in the pleasantest and most unsuspecting frame of mind. After answering Caffyn's note he had met the Langtons as they came out of church and returned with them to lunch. Dolly was herself again now, her haunting fears forgotten with the happy ease of childhood, and Mabel had made Mark feel something of the gratitude she felt to him for his share in bringing this about. He had gone on to one or two other houses, and had been kindly received everywhere, and now he was looking forward to a quiet little dinner with the full expectation of a worthy finish to a pleasant day. Even when he mounted the stairs of the house which had been once familiar to him, and stood in Holroyd's old rooms, he was scarcely affected by any unpleasant associations. For one thing, he was beginning to have his conscience tolerably well in hand; for another, the interior of the rooms was completely transformed since he had seen them last.

Then they were simply the furnished apartments of a man who cared but little for his personal well-being; now, when he passed round the handsome Japanese screen by the door, he saw an interior marked by a studied elegance and luxury. The common lodging-house fireplace was concealed by an elaborate oak over-mantel, with brass plaques and blue china; the walls were covered with a delicate blue-green paper and hung with expensive etchings and autotype drawings of an æsthetically erotic character; small tables and deep luxurious chairs were scattered about, and near the screen stood a piano and a low stand with peacock's feathers arranged in a pale blue crackle jar. In spite of the pipes and riding-whips on the racks, the place was more like a woman's boudoir than a man's room, and there were traces in its arrangements of an eye to effect which gave it the air of a well-staged scene in a modern comedy.

It looked very attractive, softly lit as it was by shaded candles in sconces and a porcelain lamp with a crimson shade, which was placed on the small oval table near the fern-filled fireplace; and as Mark placed himself in a low steamer chair and waited for his host to make his appearance, he felt as if he was going to enjoy himself.

'I shall have my rooms done up something in this way,' he thought, 'when my book comes out.' The blinds were half drawn and the windows opened wide to the sultry air, and while he waited he could hear the bells from neighbouring steeples calling in every tone, from harsh command to persuasive invitation, to the evening services.

Presently Caffyn lounged in through the hangings which protected his bedroom door. 'Sorry you found me unready,' he said; 'I got in late from the club somehow, but they'll bring us up some dinner presently. Looking at that thing, eh?' he asked, as he saw Mark's eye rest on a small high-heeled satin slipper in a glass case which stood on a bracket near him. 'That was Kitty Bessborough's once—you remember Kitty Bessborough, of course? She gave it to me just before she went out on that American tour, and got killed in some big railway smash somewhere, poor little woman! I'll tell you some day how she came to make me a present of it. Here's Binney with the soup now.'

Mrs. Binney sent up a perfect dinner, at which her husband assisted in a swallow-tailed coat and white tie, a concession he would not have made for every lodger, and Caffyn played the host to perfection, though with every course he asked himself inwardly, 'Shall I open fire on him yet?' and still he delayed.
