A sister didn’t want to face her brother’s depression. Tania Pérez Cid’s La stratégie du chat noir dive us into a world of heavy medication and suicidal thoughts. Two chairs, two side lamps, a manual typewriter and a portable cassette player set a 90’s bedroom in Mexico City. Two actresses would recreate an internal monologue in a dual way. Internal plurilingual voices drive Estefanía/Stéphanie towards a secluded world where she cannot help her schizophrenic brother nor her father who while being present is always absent: La stratégie du chat noir c’est la seule solution.
