In 2020, a 14-page comic biography of Caritat del Río made Pep Brocal (Terrassa, 1967) the first winner of the Premi ARA de Còmic. A few years later, the cartoonist revisits and expands that project in the form of a graphic novel – published by Garbuix in Catalan and Spanish – to continue exploring the chiaroscuro of one of the most mysterious figures of the 20th century, a spy in the service of communism who pulled the strings of history.
