“The wards I placed on the door to keep Reardon out of his office sealed the room behind us.” He withdrew, a few inches at least. “There was no cell reception. With the building warded against wraiths, I didn’t know you were in danger until we concluded our latest experiment, and I stepped out to check in with Cletus.”
So he leaves her with a wraith as a protector who can’t get into the building. Then puts himself incommunicado by being in an office where he can’t get cell calls or communicate with Cletus. Seems pretty suspicious. And stupid for a potentate.
