Let him fly far.
Not in this land shall he remain uncaught.
And found – dispatch.

– William Shakespeare

King Lear, Act 2, Scene 1. Edgar has fled his father Gloucester’s castle after being tricked by Edmund. Gloucester vows that Edgar will be caught and executed if found. The Earl has been duped by Edmund into believing that Edgar was involved in a murder plot against his father. But Edgar is innocent and hasn’t betrayed his father, who is simply blinded by Edmund’s lies.
