In Act 4 of "The Crucible," what does Parris think Abigail has done?

In Act IV of The Crucible Reverend Parris has discovered that Abigail has broken into his safe, stolen money, and fled town. Parris understands that this reveals her true character, and that she is only thinking of her own survival. Abigail's actions reveal that Parris and the others assisting in the investigation should be weary of Abigail's many accusations. This move begins to reveal that the entire investigation is merely a dangerous house of cards built on the villagers hysteria.
