Is The Perfect Couple coming back?

Amelia Sacks is about to marry into one of the wealthiest families on Nantucket. Her disapproving future mother-in-law, famous novelist Greer Garrison Winbury, has spared no expense in planning what promises to be the premiere wedding of the season - until a body turns up on the beach. As secrets come to light, the stage is set for a real-life investigation that feels plucked from the pages of one of Greer's novels. Suddenly, everyone is a suspect.
