She turned her taxi-cab abruptly when she was certain of being followed, went back into London, turned again and made for Westridge’s great stores in Oxford Street. The grey man ticked up two pences in pursuit. All along the Brompton Road he pursued her with his nose like the jib of a ship.

She was excited and interested, and not nearly so shocked as she ought to have been. It didn’t somehow jar as it ought to have jarred with her idea of Sir Isaac. Watched by a detective! This then was the completion of the conditional freedom she had won by smashing that window. She might have known....

She was astonished and indignant but not nearly so entirely indignant as a noble heroine should have been. She was certainly not nearly so queenly as Mrs. Sawbridge would have shown herself under such circumstances. It may have been due to some plebeian strain in her father’s blood that over and above her proper indignation she was extremely interested. She wanted to know what manner of man it was whose nose was just appearing above the window edge of the taxi-cab behind. In her inexperienced inattention she had never yet thought it was possible that men could be hired to follow women.

She sat a little forward, thinking.

How far would he follow her and was it possible to shake him off? Or are such followers so expert that once upon a scent, they are like the Indian hunting dog, inevitable. She must see.

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.
