I’m sometimes surprised by the words I use, and don’t use, in books.
From Protector of the Grey House:
Natalia sat on the edge of the tub, and watched as the light danced off the mirrors and reflected off the tiles. That ought to confuse the cameras enough. She wanted a little bit of privacy and time to examine the room. In the security room, she deduced Vincent must have a secret room. The entrance was probably in the bathroom, which is why he turned off the security cameras in here. All the doors leading to the bathroom were locked, and the keys were in her pocket. The werewolves and vampires could break down any locked door, so she only gained a minute or two per door by locking them. She would have this puzzle figured out before anyone came in, anyway.
