The staff had been notified in writing.

It was in the employment file.

Rosamund had signed the acknowledgment on the eleventh of December along with everyone else.

Sabina had not signed anything, because Sabina was not an employee.

Sabina had been in Aspen that week, and by the time she came back the installers were gone and the units were flush-mounted and painted to match the trim, and nobody had thought to mention it to her, because why would they.

She had lived in that house for four months without ever knowing she was on camera.
