a spider’s web might increase as the spider spun it quietly over one, throwing out threads so impalpable that one could not brush them away because they were too slight to be seen.  She was aware that in the first years of his married life he had alternately resented the scarcity of the invitations sent them and rudely refused such as were received.  Since he had returned to find her at Stornham, he had insisted that no invitations should be declined, and had escorted his wife and herself wherever they went.  What could have been conventionally more proper—­what more improper than that he should have persistently have remained at home?  And yet there came a time when, as they three drove together at night in the closed carriage, Betty was conscious that, as he sat opposite to her in the dark, when he spoke, when he touched her in arranging the robe over her, or opening or shutting the window, he subtly, but persistently, conveyed that the personalness of his voice, look, and physical nearness was a sort of hideous confidence between them which they were cleverly concealing from Rosalie and the outside world.

When she rode about the country, he had a way of appearing at some turning and making himself her companion, riding too closely at her side, and assuming a noticeable air of being engaged in meaningly confidential talk.  Once, when he had been leaning towards her with an audaciously tender manner, they had been passed by the Dunholm carriage, and Lady Dunholm and the friend driving with her had evidently tried not to look surprised.  Lady Alanby, meeting them in the same way at another time, had put up her glasses and stared in open disapproval.  She might admire a strikingly handsome American girl, but her favour would not last through any such vulgar silliness as flirtations with disgraceful brothers-in-law.  When Betty strolled about the park or the lanes, she much too often encountered Sir Nigel strolling also, and knew that he did not mean to allow her to rid herself of him.  In public, he made a point of keeping observably close to her, of hovering in her vicinity and looking on at all she did with eyes she rebelled against finding fixed on her each time she was obliged to turn in his direction.  He had a fashion of coming to her side and speaking in a dropped voice, which excluded others, as a favoured lover might.  She had seen both men and women glance at her in half-embarrassment at their sudden sense of finding themselves slightly de trop.  She had said aloud to him on one such occasion—­and she had said it with smiling casualness for the benefit of Lady Alanby, to whom she had been talking: 

“Don’t alarm me by dropping your voice, Nigel.  I am easily frightened—­and Lady Alanby will think we are conspirators.”

For an instant he was taken by surprise.  He had been pleased to believe that there was no way in which she could defend herself, unless she would condescend to something stupidly like a scene.  He flushed and drew himself up.
