The steam that rose from the surface was invisible in the darkness, but he could feel the cloud of warmth that enveloped the pool.He had not turned on any lights when he had come downstairs a few minutes ago. He had left the underwater lamps inside the tub off, too. The only illumination on the deck came from the cold glow of the moon and the stars.He stretched his arms out along the edge of the tub on either side and leaned back to contemplate the late-night sky. It was after two in the morning. He and Elizabeth had returned to the house shortly before one.As far as he could tell, she had gone straight to sleep, which, for some obscure reason, irritated him. How could she drop off so easily while he lay there staring through the glass at the night-shrouded mountain? The answer was all too obvious. The fact that he was in a bed a short distance away from her didn’t affect her one damn bit.He had eventually concluded that he might be able to think more clearly out here in the hot tub.
