A twenty-five year old heiress stood talking to a friend outside a bookshop. A moment later she vanished, never to be seen again. As one newspaper remarked, “she disappeared from one of the busiest streets on earth, at the sunniest hour with thousands within sight and reach,” leading the world to wonder, how? Her disappearance remains unsolved and is now named New York’s oldest cold case.
