Summer of 1937. The Estado Novo reached its peak and Salazar rules in Dictatorship. Agostinho Lourenço, maximum head of the State Surveillance and Defense Police, built the main weapon to perpetuate the power of the Dictator. The continued repression led to the creation of the Tarrafal camp in Cape Verde, where the main opposition leaders are in exile. It is in this context that a portentous bomb attack against Salazar is launched. But a miscalculation in the placement of the bomb thwarted the attack on the President of the Council. The explosion was violent, but it did not even hurt him. Things did not go well, which triggered a manhunt. But who were ultimately responsible?
