The Barber of Seville
When Basilio suddenly appears, Almaviva bribes him with some money and he goes away saying he is sick. Bartolo realizes in the end that it is a trick, and gets everyone out of the room. He goes to a notary to get a marriage contract made between himself and Rosina. He shows Rosina the letter she wrote to "Lindoro", and makes her think that Lindoro is a servant and cunning friend of Almaviva.
