Mesmo, segundo conta a xornalista Rosa Solbes, nalgunhas contornas chegouse a pensar que María Cambrils era o pseudónimo dun home ata que se lograron testemuños de sobreviventes que ofreceron datos concretos da autora, como o veterano cenetista Leonardo Herández ou Juan Bautista Pons garda de asalto durante a Segunda República.
