The prudent Pinto, ever on the watch, took care to place several of the conspirators as spies in different parts of the palace: these men walked to and fro unheeded, and were regarded merely as making part of the idle throng who generally flock about a court. On the eve of the day intended to commence by the death of Vasconcellos, they perceived that minister embark on the Tagus; this circumstance, which would have passed unnoticed by indifferent spectators, who could never have believed themselves interested in his crossing the river, spread universal alarm amongst the conspirators, and they were instantly convinced that this artful and able minister had not only discovered their project, but was gone to the opposite shore for the purpose of collecting together the troops which were quartered in the neighbouring villages. Tortures and death immediately presented themselves in the most dreadful colours to their terrified imagination; they fancied their dwellings already surrounded by the officers of justice, and some amongst them were even on the point of escaping the cruelty of the Spaniards, by flying to England or Africa. Thus passed the greatest part of the night, in all the agonies of fear and despair; but joy soon succeeded to terror, on being informed by those of their friends who had remained at the port to make observations, that the minister was just returned, hautboys gayly playing, from a grand festival, to which he had been invited. Satisfied that no suspicion was entertained in the palace, where all was buried in sleep, unconscious of the danger of the morrow, they retired at a very late hour.
