You mean, Hilde's psychic detection of Cade's visit to her apartment? That occurred in a later chapter. The visit, itself, comprised the entirety of ch. 19.

Author's Response:

Cade had been here, in her house. A smile touched her face and she nodded approvingly. She hadn’t anticipated this move. He had taken the game to a whole other level and in so doing, he’d inadvertently cleared the articles of the Covenant, permitting her to now play with him as she wanted, no restrictions. Dropping her keys back into the purse, she walked down the hall and set the bag on the kitchen table. Closing her eyes, she allowed power to flow through her. In her mind’s eye, she could visualize the policeman’s movements through her home, like a heat signature of everywhere he roamed after he had violated her private sanctum. Following the spectral image of Cade, she traced his path, looking where he looked to see what he might have seen. She wondered how he processed hi s information, what did he perceive, interpret the elements of her long life? She knew he lingered at Agrippa’s helmet and sword.
