His feet carried him through St. James Park, down an ambling dirt path that ran beside the river. The sun was setting, and the air was crisp if not clean, a fall breeze fluttering the edges of his black coat. He came upon a wooden footbridge that spanned the stream, and his boots sounded softly as he crossed it. Kell paused at the arc of the bridge, Buckingham House lantern-lit behind him and the Thames ahead. Water sloshed gently under the wooden slats, and he rested his elbows on the rail and stared down at it. When he flexed his fingers absently, the current stopped, the water stilling, smooth as glass, beneath him.
