With his hand on the knob of the door he hesitated. Through the glass top he had just caught sight of a figure that seemed familiar. He had seen that tweed before; the short girl with her back to him was wearing the dress in which he had seen her on the Wednesday night, searching among Lord Ashiel's papers in the library at the castle. It was Julia Romaninov beyond a doubt, and Gimblet drew back quickly and took up his position behind the funnels on the after-deck. In spite of the rain he remained there until the boat reached Crianan, leaning against the rail with his collar turned up and his soft felt hat pulled down over his ears, so that little of him was visible except the tip of his nose. His mind, always active, was busier than usual as he watched the ripples roll away in endless succession from the sides of the _Inverashiel_--which looked so strangely less white on closer inspection--or followed the smooth soaring movements of the gulls that swooped and circled around her, as she puffed and panted on her way across the black, taciturn waters. As they drew near to Crianan he concealed himself still more carefully behind a pile of crates, and not till Miss Romaninov had left the steamer did he emerge from his hiding-place and step warily off the boat. The young lady was still in sight, making her way up the steep pitch of the main street, and the detective followed her discreetly, loitering before shop windows, as if fascinated by the display of Scottish homespuns, or samples of Royal Stewart tartan, and taking an extraordinary interest in fishing-tackle and trout-flies. But, though the girl looked back more than once, the little man in the ulster who was so intent on picking his way between the puddles did not apparently provide her with any food for suspicion; and she made no attempt to see who was so carefully sheltered beneath the umbrella he carried. At last they left the cobble-stones of the little town and emerged upon the high road, which here ran across the open moorland. It was difficult now to continue the pursuit unobserved: and Gimblet became absorbed in the contemplation of an enormous cairngorm, which was masquerading as an article of personal adornment in the window of the last outlying shop. From this position--not without its embarrassments, since a couple of barefooted children came instantly to the door, where they stood and stared at him unblinkingly--he saw the Russian advancing at a rapid pace across the moor; and, look where he would, could perceive no means of keeping up with her unobserved upon the bare side of the hill.
