Evidence is the culmination of six years of work on political disappearance. Years ago the artist's father-in-law, a Libyan opposition leader, was kidnapped and never seen again.

The first third of the volume is a meditation on absence, told through images and excerpts of letters written to the missing man. Slowly it changes, as it becomes clear that his actions have implications for her own life and her family's safety. As she travels through London, Libya, Italy and California, the frames and diary entries take the reader on a journey through contemporary history. Crafted as an homage to one man, it shows the cruel effects of a dictatorship on intimate relationships and on family life.
