This book seeks to illuminate the shadowed and complex chapter of Bach’s life that unfolded after he left Birmingham to complete his studies in London. The breaking of his engagement to Nora Stephens had had a profound effect, yet over the following five years he somehow managed to secure both graduate and postgraduate qualifications while navigating two marriages, one death, and fatherhood - though not necessarily in the conventional order.

Read on to discover the full story and what caused his own close brush with death, why he never divorced his second wife and how he came to wash his hands of his daughter. Find out, too, what ultimately led him, in 1930, to close down his research laboratory and leave London for Wales with a young physiotherapist called Nora Weeks.
