That, too, worried her.
She tried to get the thing out of her mind, but she could not.

She had a sort of foreboding that her new friend had not spoken without reason, a feeling of insecurity as though something were impending over her.
The crisis came sooner than even Constance had anticipated when she called on Anita Douglas.

It was early in the afternoon, while Anita was still brooding, that a strange man called on her.

Instinctively she seemed to divine that he was a detective.

He, at least, had the look.
"My name," he introduced himself, "is Drummond." Drummond paused and glanced about as if to make sure that he could by no possibility be overheard.
"I have called," he continued, "on a rather delicate matter." He paused for effect, then went on: "Some time ago I was employed by Mr.Douglas to--er--to watch his wife." He was watching her narrowly to see what effect his sudden remark would have on her.
