Rubies for Christmas - Short Stories

Roxanne Wilder is spending Christmas in Wilton, Illinois, with her family.  She agrees to help the Women's Guild Decorating Committee prepare for the senior holiday luncheon at the Old Hall, but when the women are snowed in, they have more to worry about than claustrophobia.  Annie Verona's gigantic ruby ring is missing, and the dreadful diva is pointing an accusatory finger at each member of the committee.
Was the ring really stolen? Or did Annie simply lose her bauble among the mistletoe decorations during the few times she condescended to help out? Roxanne has until the snow plow shows up to figure out who did the crime, or reputations with suffer.
