Lord Chamberlain John spends his days counseling Emperor Justinian and passes the small hours of night in conversation with the solemn-eyed little girl depicted in a mosaic on his study wall. He never expected to meet her in a public square or afterwards find her red-dyed corpse in a subterranean cistern.
