From the growing tower the little party turned west toward the sunset, walking slowly over a rough roadway made of cinders and slag. Once a cinder penetrated Lily's frail shoe and she was forced to lean against Willie while she took it off and removed the offending particle. He supported her politely and turned away his face so that he should not offend her by seeing her shapely stockinged foot.
