The crucible is a play written by Arthur Miller. Parris has requested Beverly's Reverend John Hale, a specialist in witchcraft, to ascertain whether Betty is actually possessed.
Abigail Williams, Betty, and a few other girls were caught dancing with Parris' slave, Tituba, in the forest in the middle of the night. Parris chastises his niece for the incident.
