César Sánchez Sánchez (Madrid, 1970) studied in the Faculty of Science and Mathematics but never practised either because, as he says, "his brain box isn't big enough". He has published the novel De vivio (On Vice; Relee, 2016) under the pseudonym Arturo G. Pavón, in addition to the short stories Ciudades en las que nunca has estado (Cities I Have Never Visited; Barrett, 2018).
