who gives macheath up to peachum and the constables
The Beggar's Opera Meanwhile, Polly visits Lucy to try to reach an agreement, but Lucy tries to poison her. Polly narrowly avoids the poisoned drink, and the two girls find out that Macheath has been recaptured owing to the inebriated Mrs Diana Trapes. They plead with their fathers for Macheath's life. However, Macheath now finds that four more pregnant women each claim him as their husband. He declares that he is ready to be hanged. The narrator (the Beggar), notes that although in a properly moral ending Macheath and the other villains would be hanged, the audience demands a happy ending, and so Macheath is reprieved, and all are invited to a dance of celebration, to celebrate his wedding to Polly.
