On April 1, 1868, a pretty young Anglo-Indian woman named Rose Brown was murdered in Calcutta, her throat slit almost ear to ear. Her body, discovered late at night by a beat constable on patrol duty, lay where she had died, mere minutes away from the Amherst Street police station. The positioning of the body made it clear that she had been on the move during the attack, perhaps trying to run away from her killer.
