A small bundle of slightly toxic herbs lie in the pouch of a deceased half-elven female. A DC 15 Heal check reveals them to be a potent abortifacient, ordinarily steeped in hot water and taken as a tea.
A notorious bandit hides a small wallet in bandages wrapped around his ankle. Tattered love letters lie within. Dated 21 years earlier, these prove that a local nobleman once courted the highwayman's mother.
The gold-chased chastity belt of a knight's daughter hides a small, locked compartment, in which she keeps a golden locket incribed with a lewd poem. She keeps the belt's key hidden elsewhere.
