Life takes a dramatic turn for Josiah when she witnesses a death at an engagement party for Matt. Matt? Yes, Matt.

Charming socialite Addison DeWitt falls into a fit after taking a sip of bourbon. That would be upsetting enough, but Josiah is sure it is murder. However, no one will believe her except for Lady Elsmere and Meriah Caldwell, the famous mystery writer. The three of them conspire to bring the murderer to justice. It turns out the suspect is always three steps ahead of them.

To make matters worse, Josiah's daughter, Asa decides to move to London, Franklin leaves town and Jake starts singing a different tune. Josiah doubts her ability to meet the future alone. Maybe it's time to sell the Butterfly and move to Florida with the rest of the old folks.
