At first she didn't understand why the bed felt so strange, then she remembered her guest and, somewhat reluctantly, dragged herself out of bed and walked down the hall to get two cups of coffee. MacKenzie, frightened by the anonymous message the day before, stayed the night with Hanna for moral support. The idea that someone invisible was watching her -- someone who wasn't even there -- seemed at least tolerable in the company of her best friend. Hanna sympathized with her feelings, even though she thought they were somewhat irrational. Why would anyone want to spy on her while she slept? And if they did, they would probably know enough about her to check Hanna's room, too. She didn't let any of this on to MacKenzie when she showed up last night, looking as if she'd seen a ghost. But under the morning sun they'd have to talk it through -- a little more objectively. MacKenzie offered to sleep in the chair again, or on the floor, but Hanna insisted they share the bed.
