When Antony Easton’s enigmatic father passes away, he goes through his Dad's suitcase, filled with cryptic clues: neatly stacked German money, a family tree he doesn’t recognise, and books filled with sprawling notes. He also finds his father’s birth certificate, but bearing a different name. Confronting his dad’s double identity, Antony begins a ten-year quest to uncover the truth. Piece-by-piece he comes to understand his family’s dark history as he attempts to reclaim his grandfather’s property and art empire, and expose the historic robbery and murder of his relatives.

The House at Number 48 is presented by Charlie Northcott.
