Set in the East End of London and in Surrey,
Time Will Tell opens towards the end of World War II, during an air-raid. Joan gives birth to a son just as a bomb hits the hospital. The electricity is cut, and panic and pandemonium ensue, but this is nothing compared to the anguish Joan will suffer in the following years. For in the aftermath of confusion, her baby son is miss-tagged with another baby boy, a fact that only comes to light 20 years later.
