Even as Jan puts the final touches on her wedding plans, mystery still swirls around the tearoom. While searching for the perfect wedding gift for Jan and Bob, Elaine and Nathan stumble upon a distinctive antique teapot at Mainely Bargains. Nathan feels certain it's the one that's been missing for 150 years from Hannibal Hamlin's historical family tea set that once served President Lincoln. After Nathan purchases the teapot, Elaine and Jan set out to help him trace its provenance. Their pursuit brings them in contact with some very interesting people, including a woman who is convinced Nathan's teapot belongs to her-- and will stop at nothing to get it back. And when Jan and Bob's big day finally arrives, it is capped by an exciting announcement and a thrilling development-- just as the newlyweds depart for their honeymoon.
