Inspector Thomas Brackenreid's wife Margereth started as wedding planner, but her first bride Elizabeth Cummersworth's much elder groom Oliver Pym is fatally electrocuted when his cane touches a floral display minutes after their vows, due to bared electric isolation. The apparent accident proves suspicious as the black widow already inherited richly from her four previous husbands after various accidents, and haughtily denies any cooperation, shielded by her coachman and companion. Looking into these old cases yields a common mystery henchman, yet identifying him isn't the conclusion. Meanwhile Crabtree organizes a writing course for budding authors, which gets few candidates, one by one dropping out discouraged or offended, except most promising Lucy Maud Montgomery from out of Toronto, whom he dates and coaches to conceive her novel.
