Tied Up in Tinsel (Inspector Roderick Alleyn, 27) (Volume 27)

It's murder at a country-house party; a Christmas party, in fact, where all the guests are eccentric, and all the household staff are former criminals. Which of them caused the disappearance of one of the players in the holiday pageant? Luckily, both Inspector Alleyn and his wife, Agatha Troy, are on hand to wrap up the case.
