Anyone Know Spanish, putting all the last of my pints into this, so please help

Passage A:

In December 1960, four months after our arrival, Time magazine reported the murder of the three Mirabal sisters, who along with their husbands had started the national underground Dominican Republic. My parents confiscated the magazine. To our many questions about what was going on, my mother always had the ready answer, "En Boca cerrado no entran moscas.” No flies fly into a closed mouth. Later, I found out that this very saying had been scratched on the lintel of the entrance of the SIM's torture center at La Cuarenta.

Passage B:

The novel would be a fictional retelling of the story of three Mirabal sisters, contemporaries of my mother, whose murder had been reported in that confiscated Time magazine. This time, my mother warned, I was not just going to anger family members, but I would be directly responsible for their lives. There were still old cronies of the dictator around who would love an excuse to go after my family, after my father, after her.

This was one of the hardest challenges I had ever had to face as a writer. If my mother were indeed speaking the truth, could I put my work above the lives of human beings? But if I shut up, wouldn't I still be fanning the members of the dictatorship with its continuing power of censorship and control over the imagination of many Dominicans?
