In this anonymous letter, written by a ‘Sad Grandmother’ and received by the Salazarist political police on 26 February 1970, the author denounces the publication of a book entitled ‘Liberdade de Amar’ (original English title ‘The Freedom of Sexual Love’). She has caught her granddaughter reading it and, after browsing through it herself, equates its content to pornography. By writing to the secret police, the ‘Sad Grandmother’ is implicitly calling for measures to be taken against the publication and circulation of such books in Portugal. Note that the title of the book has been underlined in red by a PIDE agent upon reception of the letter, indicating that its content was taken seriously by the secret police.
