My name is Jack Reacher.
No middle name, no address.
I'm a man with a rule.
People leave me alone, I leave them alone.
If they don't, I don't.

As every Reacher fan knows, you don't have to break the rules if you make the rules.

Rule 1. NEVER VOLUNTEER FOR ANYTHING
Rule 2: BE ON YOUR FEET AND READY
Rule 3. SHOW THEM WHAT THEY'RE MESSING WITH
Rule 4: DON'T BREAK THE FURNITURE
Rule 5: IF IN DOUBT, DRINK COFFEE
