The _bravo_ followed him and discovered from his servant where he lodged.
Accordingly, he engaged rooms in the Rue S.Honore, in order to be nearer to his victim.
Some time, however, elapsed before he was able to ascertain Troilo's daily habits.

Chance at last threw them together.

He was playing _primiero_ one evening in the house of an actress called Vittoria, when Troilo entered, with two gentlemen of Florence.

He said he had been absent ten days from Paris.

Ambrogio, who had left his harquebuss at home, not expecting to meet him, 'was consequently on that occasion unable to do anything.' Days passed without a better opportunity, till, on November 30, 'the feast of S.Andrew, which is a lucky day for me, I rose and went at once to the palace, and, immediately on my arrival, saw him at the hour when the king goes forth to mass.' Ambrogio had to return as he went; for Troilo was surrounded by too many gentlemen of the French Court; but he made his mind up then and there 'to see the end of him or me.' He called his comrade Hieronimo, posted him on a bridge across the Seine, and proceeded to the Court, where Troilo was now playing racquets with princes of the royal family.
