Next day he was about early at the loch-side, and though he contrived to arouse no suspicion in the minds of either those connected with the hotel or any of his fellow-visitors, he kept casual observation upon the pair. Now and then he would accidentally be so close in their vicinity as to be able to overhear scraps of their conversation. Yet so cleverly did he do this, and so utterly uninterested did he appear to be, that even Ena, who was ever suspicious of eavesdroppers and persons watching, failed to realise the intense interest which she had evoked in the little round-faced man.
The following day Ena accompanied her friend on a trip across to Loch Katrine, but the stranger idled about the hotel and wrote letters. After lunch, however, at the hour when the small establishment was quietest, the curiosity of anyone watching him would certainly have been aroused. His actions were truly a little peculiar.
At about three o'clock that afternoon, having ascertained that none of the servants were about, he slipped silently to Mrs. Pollen's bedroom, the door of which was unlocked, and, entering quickly, closed the door after him. Then, walking straight to a big dressing-case which lay upon a chair near the window, he took out a bunch of keys and tried one after the other in an effort to open it.
He failed, none of the keys would fit.
"If I force it she'll suspect," he murmured. "No, I must give it up for the present—curse it!"
Then he made a tour of the room, opened the wardrobe, and examined the contents of several drawers, but though some expensive jewellery was there, he cast it aside in contempt.
Mr. Greig did not want jewels. It was evident that he was in search of something else far more interesting. But that lock upon the dressing-case was an unusually good one, and had defied all his many keys.
There was but one course to pursue, and that was to retreat to his own room, which he did in great disappointment and chagrin.
That evening he watched the two women on their return. His movements were those of a practised watcher. He was unobtrusive, disinterested in everything save the picturesque surroundings, and behaved as though he had no interest whatever in any person in the hotel.
That evening, while in the garden after dinner, he found himself sitting on a seat beside Mrs. Morrison, and ventured to address a remark to her regarding the glorious sunset.
