It should be observed that although Sara sat close to the open window, she was not liable to be seen by the passers-by in the street, did any cast their eyes that way. A small stand or ledge had been constructed round the window (a bay window, as was the one answering to it on the other side, the drawing-room), and this was filled with pots in flower. Geraniums of many species, fuchsias, heliotropes, heaths, wild thyme, the fine flowering cactus, and many others, raised their heads proudly, and formed a screen behind which Sara was securely sheltered from observation, and also from the rays of the gas-lamp at the gate, which otherwise would have lighted her up. So that, although she could see out perfectly well, sitting as she now was, she could not be seen. If she chose to stand at the window and lean out, her head was above the flowers; but at the same time they entirely prevented her from seeing anything immediately below her window. The ground for a yard or two beyond Dr. Davenal's study window was as completely hidden from her as though it had been a hundred miles off; and it is necessary to mention this. The bedroom above Sara's, occupied by Watton the upper maid, had a flat window, and its view underneath was in like manner obstructed by the extending bow and the plants in it of Sara's. These flowers at Miss Sara Davenal's window were quite the admiration of the pedestrian portion of Hallingham, and many a one would halt at the front railings to take a passing gaze at them. They were really beautiful, and Sara took a pride in them and liked to tend them. She liked to inhale their sweet perfume, as she was doing now, sweeter and stronger in the night air than in the garish day. Perhaps the heliotrope was of all the most powerful scent: and somehow that heliotrope had become associated in her mind with Mr. Oswald Cray. She could not have told why or wherefore; she had never attempted to analyse the cause: she only knew that when she approached that window, and the perfume of the heliotrope was wafted to her senses, the image of Oswald Cray was, in like manner, by some mysterious instinct, wafted to her mind. Perhaps it did not require any extraneous aid to bring him to her memory. He was already too securely seated there. For the last twelvemonth, since Oswald Cray had become intimate at their house, her love for him had been gradually growing into being: that subtle understanding, never to be explained or accounted for, which draws together two human hearts, and only those two, the one for the other, of all the whole world, life finding life, had arisen between them. Oswald Cray had never spoken or hinted at his feelings until the time when Dr. Davenal honestly avowed to him that he had fancied he cared for Caroline: that had brought forth the one word--and it was little more--to Sara. But she had known it just as surely as though he had spoken out all along.
