The conspirators, once relieved from all apprehensions of discovery, without the smallest compunction for the enormity of their crime, turned their thoughts towards a second attempt, and the means of making it a successful one. The spot chosen for their private meetings, was a garden belonging to Tavora, which also served as a place of rendezvous to a foreign servant, who carried on a clandestine correspondence with a woman in the house: she, one night, failing in her appointment, her lover concealed himself in the garden, near the very spot where the conspirators held their assembly. Not one word which passed escaped the ears of the attentive listener, who, by that means, became acquainted not only with every particular relative to the first attempt, but with the plan laid for the execution of the second. This man, no sooner contrived to quit the garden, than he flew to the prime minister, and related with the utmost precision every thing which had passed. Carvalho instantly perceived the imminent danger to which he was exposed; and having now the most convincing proofs, of what before he only suspected, nothing remained to be done but to deliver up the criminals to the severity of the law: he, however, still continued to dissemble; and the duke d'Aveiro, either from his own apprehensions, or by the advice of his friends, having asked leave of absence for three months, it was immediately granted, and that in the most obliging and flattering manner. The marquis de Tavora was at the same time appointed to a commandery, which he had solicited during several years. Favours thus repeatedly conferred on the principal conspirators, completely put an end to the apprehensions of their friends, relations, and accomplices. The public was likewise deceived; every thing which had passed was buried in oblivion; and nothing was talked of but the intended marriage between the daughter of Carvalho, and the comte de Sampayo, with the entertainments which would naturally take place on so brilliant an alliance. The king himself signed the contract of marriage, promised to defray the expences of the wedding, and invited all the grandees of the kingdom to be present on the occasion. The duke d'Aveiro no sooner received this intelligence, than he left the country, and repaired with all possible haste to Lisbon; where every thing around him wore the face of joy and pleasure; but on the very day when the court and city were busily employed in preparing for two balls, the one at the prime minister's at Belem, and the other in Lisbon, at the _long room_;[43] intelligence was brought that troops, composed both of horse and foot, had unexpectedly entered the city, and that great numbers of persons of all ranks and descriptions had been taken into custody.
