This is a book about boundaries — and relationships. At its heart is the eponymous house by the lake, which in 1927 was the first of many small wooden summer houses to be built in the village of Gross Glienicke. Both its situation, just outside Berlin in the lakeside area that would later abut Gatow airport, and its many occupants, from well-established German Jews to partying neo-Nazis, would expose the property to the more tidal waters of modern German history.
