Confessions of the Sullivan sisters / Standiford, Natalie

Upon learning on Christmas Day that their rich and imperious grandmother may soon die and disown the family unless the one who offended her deeply will confess, each of the three Sullivan sisters sets down her offenses on paper.

When the Sullivan sisters' grandmother gathers the entire family on Christmas to announce that she is removing them all from her will unless whoever it is that has offended her confesses in writing by New Year's Day, everybody begins to consider what they may have done.
