This plan was executed in one night. Shortly before daybreak Tarquin summoned the Latin chiefs into his presence as though something had happened to give him great alarm. He told them that his delay on the previous day had been brought about by some divine providence, for it had proved the salvation both of them and himself.
He was informed that Turnus was planning his murder and that of the leading men in the different cities, in order that he might hold sole rule over the Latins. He would have attempted it the previous day in the council; but the attempt was deferred owing to the absence of the convener of the council, the chief object of attack.
Hence the abuse levelled against him in his absence , because his delay had frustrated the hopes of success. If the reports which reached him were true, he had no doubt that, on the assembling of the council at daybreak, Turnus would come armed and with a strong body of conspirators.
It was asserted that a vast number of swords had been conveyed to him. Whether this was an idle rumour or not could very soon be ascertained, he asked them to go with him to Turnus.
The restless, ambitious character of Turnus, his speech of the previous day, and Tarquin's delay, which easily accounted for the postponement of the murder all lent colour to their suspicions. They went, inclined to accept Tarquin's statement, but quite prepared to regard the whole story as baseless, if the swords were not discovered.
