Charles Dickens, Illya's and Waverly's Xmas story

[jsks]

Looking for a Xmas story in which Napoleon goes out on Christmas eve (illya turned done going out together) and Illya deals with the ghosts of Xmas, with Napoleon arriving back in time to unravel Illya from the bedsheets.
Mr. Waverly's story has him finding out that his wife knew about an affair he had during WW2 and thought he kept from her.
