Epilogue
Adam and Joan were too involved with each other to notice a figure standing on the bank of the lake watching them through binoculars and being very pleased with herself for helping a friend out.
"That's why we painted the boat," Grace Polk says to herself.
She shouldn't be spying on them, but she just had to know if the yellow boat was Joan's gift to Adam. She had kind of suspected it all along, but now she knew for sure that she had been right.
