Summary

You play as Katharine, a young woman invited to her friend's engagement party. The atmosphere is getting awkward during dinner and worse yet, the next morning the pink diamond engagement ring is missing! While a bitter ex-boyfriend is an obvious first suspect, everyone in this close circle of friends and relatives seems to have something to hide.
