Overview: David uncovers the extraordinary stories of a woman widowed in a cholera epidemic who turns the house from a single dwelling into a boarding house. He follows the trail of an ambitious Jewish immigrant from Denmark, struggling to stay afloat in the midst of a global financial crisis, and then sees what happens to a wheeler-dealer whose job is to enable hundreds of people to make new lives in America. David also traces the extraordinary story of the Robinsons - a seemingly successful couple in the watchmaking business. For them, the house is the backdrop to a family drama involving violence, infidelity and a tangle with the divorce courts. The story ends on the banks of the River Mersey, where an unidentified body dragged from the water has surprising connections to the house.
