But if she say she is pregnant, then she must be! That woman will never lie, Mr. Danforth.

– Arthur Miller

The Crucible, Act 3. Here John Proctor responds to Judge Danforth’s skepticism about Elizabeth’s claim that she is pregnant. This would earn her a reprieve from hanging at least until her baby is born. John assures Danforth that his wife never lies. His words turn out to be ironic, because Elizabeth will lie to the court about John’s cheating with Abigail in order to protect his reputation.
