It was later still, after considerable noise downstairs, that they made their way upstairs. I could tell she was naked but for her shoes and he was still fully clothed, save for his blazer which I could only assume was with her dress and underthings. His shirtsleeves were rolled up.

"Show me." His baritone was the first verbal sound I heard since they left.
