      as, to detect a crime or a criminal; to detect a mistake
      in an account.

            Plain good intention . . . is as easily discovered
            at the first view, as fraud is surely detected at
            last.                                 --Burke.

            Like following life through creatures you dissect,
            You lose it in the moment you detect. --Pope.

            He was untruly judged to have preached such articles
            as he was detected of.                --Sir T. More.
