Trace Evidence is a work based on the emergence of material belonging to Czech artist and film maker Ester Krumbachová. The work explores the relationship between the techniques of police work and the techniques of the archivist. Using photographs that chart the construction of an archive in Prague dedicated to Krumbachová, period maps of the city, texts by her and a secret service file, the work will present a police-style 'crazy wall' where her life can be pieced together.
