"Thank Heaven! That's over! The first few hours when one cultivates a friendship are always full of pitfalls. A word in the wrong place, and the person one seeks to know may instantly conceive a strong dislike. In this case, however, the woman has approached me. It was a good job I got up here first."

Ena Pollen was much fatigued by the recent rapid journeys to and fro to Scotland, over to Paris and back, and then north again to Loch Lomond. She was, however, a cosmopolitan, and had travelled very extensively ever since she had been left a widow ten years earlier. Her husband had been a solicitor, whose practice was in Bedford Row, but after his death she had embarked upon an adventurous career which had culminated in her association with Bernard Boyne and his wife.

That association had brought her considerable wealth—sufficient, indeed, to allow her, through payments from Boyne and his wife, to live in an expensive flat and indulge in jewellery, furs, smart frocks, and all that appealed to her natural vanity.

That evening, however, she felt worn out. The strain of ingratiating herself with Mrs. Morrison of Carsphairn, whom she found to be an exceedingly shrewd woman, had been considerable, and this, combined with the fact that she had taken a long walk that afternoon, had utterly fagged her.

From a tiny silver tube with a cap upon it, which she took from her dressing-case, she extracted a single little white tabloid, and swallowed it.

"I wonder—I wonder if we shall really be successful?" she murmured to herself. "There must be no slip this time—no recurrence of that unfortunate contretemps in the Martin affair. Phew! That was a narrow shave. I was in Melun only just in time. A few days later, and all chance of dispelling suspicion would have gone!"

She reflected how on more than one occasion they had sailed very near the wind—far too near to be pleasant—and how they had narrowly escaped a closer inquiry. Lilla, however, was always fearless, even when her husband expressed doubts. It was she, indeed, who was the moving spirit of the whole affair, for she went about in her circle of society with her eyes and ears ever open until she saw an opportunity to put into motion that deadly machinery which, worked with such subtle cunning, never failed to increase their bank balance.

She stood at her window as the full moon rose over the loch, transforming the scene into a veritable fairyland, and here she remained in deep reflection. She was contemplating the course she should pursue when she met Mrs. Morrison on the morrow. Already they had become friends, the widow from Kirkcudbrightshire being, of course, in entire ignorance that the pleasant woman from London had come to Ardlui for the sole purpose of making her acquaintance. Ena Pollen was possessed of a cunning that few women possess unless they are adventuresses. She saw that she must allow this Mrs. Morrison to seek her society. Already she realised that the Scotch widow had been greatly attracted by her conversation; hence she decided that on the morrow she must not be too eager to meet and chat with her.

She was in no mood for sleep, therefore she pulled down the blind, and seating herself at a little table in the room, penned a letter which she addressed to "B. Braybourne, Esquire, 93, Pont Street, London," and in the course of which she wrote:

"Things are going even better than I expected. Mrs. M., who made the first advance, is extremely affable to me. I hope that within a week or ten days I can be back in London. Mrs. M., on leaving here, is going to Brighton to visit a niece, so I may see something of her. Do not write here, as I may be leaving any day. I have had a letter from Emery. It was sent to Upper Brook Street, and fortunately enclosed to me in an envelope. It would have been unfortunate if it had come here addressed to Mrs. M.! Would it not? But do not be alarmed! I have given instructions that no letters are to be forwarded in future."
