While Molly Pink knits together an idea for a new project, Miami Wilson busily converts a house she inherited into a rental property. But Miami is left shorthanded when Sloan Renner, the woman helping her clean out the house ends up dead. A large drone had flown over the property discarding mollusc shells all over the backyard. Was it an accident? An ill-fated prank? Witnesses clam up when Molly's ex, homicide detective Barry Greenberg, tries to get information, but he thinks Molly may be able to get them to open up to her. When Molly learns about Sloan's seafood allergy, she suspects that the woman's death was no accident.
