"To make up for a few things," he said, turning to leave.

With that, he walked out and quietly closed the door.

She went to the bathroom, then put on a bathrobe and headed out into the hallway. The nurse's station was not occupied. Marion was still in the kitchen on the first floor, presumably.

Good.

She was feeling shaky, not nearly as strong as she'd initially thought she was, but she pressed on, taking the elevator, her first use of Grant's Gerex master key. She bypassed the first floor and an instant later she was stepping into the basement's laboratory area.

At the moment it appeared to be entirely deserted, though the fluorescent lights bathed the space in a stark, pitiless light.

Down the hall was Dr. Van de Vliet's office and the examining room, where she and her mother had gone when they were being admitted. At this time of night, everything was closed and probably locked.

She turned and looked at the forbidding entryway to the glass‑enclosed laboratory. Through the transparent walls she could see the dim glow of CRT screens and incubators filled with petri dishes. And there at the back was—could her eyes be trusted?—the outline of an elevator door. She hadn't noticed it until this minute. It seemed to be built with a nod toward camouflage.

It could lead to Kristen, she told herself. Find out what Grant is so freaked about. He can wait a couple of minutes.
