There are four days between Southampton and the iceberg - four days in which history handed two thousand people an enclosed world of extraordinary beauty and suspended consequence. The RMS Titanic's maiden voyage was not merely a crossing. It was, for its first-class passengers, a social theater unlike any other: a floating palace of mahogany, silk, and crystal where the hierarchies of the Edwardian age were simultaneously observed and, in the particular intimacy of a ship at sea, quietly transgressed. Between One World and Another is a work of historical drama that uses the documented physical and social world of the Titanic as the architecture for imagined human relationships - characters drawn from the spectrum of shipboard society, placed with precision into spaces that the historical record has preserved in extraordinary detail. Its protagonists move through rooms that actually existed: the first-class Reading and Writing Room, its great bow window framing the North Atlantic in late afternoon light, its white-painted walls warm against the cold outside; the Turkish Bath on F-Deck, where the ship's gymnasium steward Thomas McCawley collected his one shilling admission dressed always in white flannels; the Grand Staircase, its glass dome admitting the flat grey sky, where first-class passengers descended to dine on ten-course menus while stewards in white livery stood at measured intervals along the walls.
