When he was a boy and returned to the family home from primary school in the afternoon, Carlo Gébler would often hear the sound of typing coming from the shed at the foot of the garden. This was where his mother, the writer Edna O’Brien, sometimes went to write her novels.

Later, when he lay in bed at night, Carlo would again hear the sound of typing. This time it would be coming from the downstairs front room where his father, Ernest Gébler, wrote plays for television.

Now 66 and an acclaimed author himself, Carlo wants to know why the children of writers often follow their parent’s footsteps into literature. Exploring the dynamics of literary lineage and his own journey into writing, Carlo asks if it is simply an iron law that the apple rarely falls far from the tree - or if the truth is something far more complex.
