In 2005, American artist Jill Magid was commissioned to produce an artwork for the AIVD – the Dutch Secret Service. At Tate Modern’s Level 2 gallery she presents the culmination of a project that saw her gain unprecedented access to the organisation. The exhibition traces her encounters with real-life secret agents as she worked towards a book – ‘Becoming Tarden’ – about trying to find a face at AIVD’s centre. TateShots met Jill in an anonymous café (around the back of Tate Modern) to find out why for her, surveillance and authority combine to make a strange kind of love story.
