At Heathrow Terminal 5's Duty Free halls, where departures are constant and nobody stays for long, Vik Bhattacharya has spent decades stuck working and avoiding the buried truths of his family. But when his father Sunjeev, once larger than life, is forced into a care home with dementia, Vik can no longer remain duty free. As Sunjeev's condition worsens, one obsession remains: he wants to see his eldest son one last time. The trouble is, nobody knows where he is. Estranged for twenty years, the oldest Bhattacharya sibling Raj vanished after a devastating family rupture. With their father's time running out, Vik and his practical but exhausted sister, Simi, must set out to find their brother and bring him home. Their search takes them through the hidden corners of Hounslow, across old grudges, buried secrets and half-forgotten family legends. As they piece together the story of the brother they lost, they uncover uncomfortable truths about themselves, their parents and the fragile nature of memory itself.
