'If you don't know, I don't know...'

'Things not discussed can never be recorded and therefore have never taken place.'

Those were the last words Michael Butler said to his younger son, Jeff, on a Saturday evening in August before Jeff left on holiday.

Jeff could not have imagined that events would unravel so fast from there, starting with the suicide of his father by hanging in their garage later that night and leading to a surprising trip to Hungary, where his father had been working for an international organisation and had become involved in investigating the trafficking of Roma girls into the sex trade.

As far as Jeff was concerned, the act of suicide causes such indescribable pain for those left behind that for anyone to even contemplate the act was inexcusable. An act of love betrayed. But was his father really responsible for taking his own life?
