In the Ukrainian city of Poltava stands a building known as the Rooster House. It doesn't look horrifying. And yet, when Victoria was a girl growing up in the 1980s, her great-grandmother would take pains to avoid walking past it.

In 2014 she came across her great-grandfather's diary, one page scored deep with the single line: 'Brother Nikodim, vanished in the 1930s fighting for a free Ukraine.' She had never heard of this uncle and no one - especially her grandmother - seemed willing to tell her about him.

Victoria became obsessed with uncovering his story. After years of sifting through Ukraine's post-Soviet bureaucracy, after travelling to tiny, ruined villages and speaking to the wizened survivors of that era, her winding search took her back to the place she had always known it would - to the Rooster House.

During a family holiday in Italy, you get an urgent call from your sister. There's been an accident: she hit a man with her car and he's dead. She's overcome with terror - fearing years in a foreign jail away from her child. She asks for your help. It wasn't her fault, not really. She'd cover for you, so will you do the same for her? But when the police come calling, the lies start. And you each begin to doubt your trust in one another.
