She paid off her taxi at Westridge’s and, with the skill of her sex, observed him by the window reflection, counting the many doors of the establishment. Would he try to watch them all? There were also some round the corner. No, he was going to follow her in. She had a sudden desire, an unreasonable desire, perhaps an instinctive desire to see that man among baby-linen. It was in her power for a time to wreathe him with incongruous objects. This was the sort of fancy a woman must control.... He stalked her with an unreal sang-froid. He ambushed behind a display of infants’ socks. Driven to buy by a saleswoman he appeared to be demanding improbable varieties of infant’s socks. Are these watchers and trackers sometimes driven to buying things in shops? If so, strange items must figure in accounts of expenses. If he bought those socks, would they appear in Sir Isaac’s bill? She felt a sudden craving for the sight of Sir Isaac’s Private Detective Account. And as for the articles themselves, what became of them? She knew her husband well enough to feel sure that if he paid for anything he would insist upon having it. But where—where did he keep them?... But now the man’s back was turned; he was no doubt improvising paternity and an extreme fastidiousness in baby’s footwear——Now for it!—through departments of deepening indelicacy to the lift! But he had considered that possibility of embarrassment; he got round by some other way, he was just in time to hear the lift gate clash upon a calmly preoccupied lady, who still seemed as unaware of his existence as the sky. He was running upstairs, when she descended again, without getting out; he stopped at the sight of her shooting past him, their eyes met and there was something appealing in his. He was very moist and his bowler was flagging. He had evidently started out in the morning with misconceptions about the weather. And it was clear he felt he had blundered in coming into Westridge’s. Before she could get a taxi he was on the pavement behind her, hot but pursuing. She sought in her mind for corner shops, with doors on this street and that. She exercised him upon Peter Robinson’s and Debenham and Freebody’s and then started for the monument. But on her way to the monument she thought of the moving staircase at Harrod’s. If she went up and down on this, she wanted to know what he would do, would he run up and down the fixed flight? He did. Several times. And then she bethought herself of the Piccadilly tube; she got in at Brompton road and got out at Down Street and then got in again and went to South Kensington and he darted in and out of adjacent carriages and got into lifts by curious retrograde movements, being apparently under the erroneous impression that his back was less characteristic than his face.
