While helping Ruby Wilcox clean up the loft above their shops, China comes upon a box of antique handcrafted lace and old photographs. Following the discovery, she hears a woman humming an old Scottish ballad and smells the delicate scent of lavender. Soon, strange happenings start to occur in Thyme and Seasons: misplaced items, a ringing bell, and the appearance of lavender sprigs in odd places. When a customer mentions seeing a mysterious woman picking flowers nearby and then suddenly disappearing, China must finally admit what Ruby has always known, their building is haunted. But by whom? As China investigates, the tragic story of a woman in one of the old photographs unfolds. Annie Laurie was a young widow who'd lost both her husband and her child in the same day. She manages to survive through her lace-making business and finds happiness again only to have a suspicious death overshadow her new life.
