Letter from Bernarda, pseudonym of Bernardo Peinador, an honorary Judge Advocate, to Manuel López, a cavalry captain.
The author informs Manuel López that some people are afraid of participating in his business because of the close surveillance they are under. He also gives the addressee instructions for preparing a good invisible ink.
The General Police Administration was closely monitoring the activities of foreign citizens residing in Portugal, also controlling their communications, in collaboration with the superintendent of the Posts. This letter is part of this intercepted correspondence from those Spanish military and intellectuals who, fleeing the absolutist Spain, had taken refuge in Portugal and were suspected of harboring liberal ideas and of plotting to overthrow Fernando VII and establish a constitutional regime.
