Wendy Robbins presents a series revisiting the childhood neighbourhoods of influential Britons. Historian and journalist Peter Hennessy returns to London. In the 1950s, Finchley was dirty, poor and full of displaced people. But for Hennessy it was a place full of optimism and confidence as a proud Britain recovered from World War II. The youngest in a large Irish Catholic family living in council-requisitioned houses, Peter discovers that these same properties are now selling for more than two million pounds.
