He checked the kitchen and had one final look around, preparing to leave. Then, looking at the keys Monica had given him, he found one labeled “wine cellar,” which she had mentioned. He looked around for a door and found one under the stairs. The light switch gave no joy, and he felt his way down the steps to the bottom, where he found another door. Feeling for the lock, he inserted the key and turned it. As he stepped into the cellar, something brushed against his cheek, and he grabbed it: a string. He pulled it, and a single light bulb came on. The wine cellar was about twelve by fifteen feet and quite full of bottles. He checked a few and found some lovely old clarets and burgundies; whoever owned the house had been laying them down for years; you couldn’t just walk into a shop and buy them anymore.

He stood in the middle of the cellar and looked at each of the four walls. Why was the cellar so small, when the house was so much larger? He examined the walls, which were covered by racking from floor to ceiling. Walking slowly around the room, he checked between each stack of racks, and finally he came to a pair that seemed somehow unlike the others. The racks were all fixed to the wall, except these two, which moved when he shook them. Pressing an eye to the crack between one rack and its immediate neighbor, he saw the dull glint of dim light on metal. A hinge, maybe?

He moved along one rack farther, peering into the small spaces between them, and he saw a flat piece of metal that seemed to connect two racks. It was recessed too far to reach with his fingers, and even his pen was too fat to fit between the racks. He looked around and saw a small table containing a decanter and a corkscrew.

He picked up the corkscrew, which was of the waiter’s type—small, flat, with a folded knife blade at one end. He opened the knife and poked it between the two racks, finding the strip of metal. It moved when poked, and he tried inserting the blade underneath the strip and pushing upward. Almost to his surprise, the metal strip moved easily. It had been holding the two racks together; now, with it out of the way, Stone pulled on the two racks and they quite easily swung into the cellar like double doors. He could now see that each rack had a solid wood back that was fixed to the wall by four heavy hinges.
