Third month in the stronghold, a limping quack selling plasters started hanging around Two-Dog.
One day while Two-Dog was practicing, Old Black suddenly charged like a mad dog, knocked the cripple flat, and rooted out a wax-sealed letter.
Gold lettering on the envelope: Secret from Palace of Eternal Trust.
Piggy chopped off the spy's other leg on the spot, blood spraying three feet, smiling innocently:
"My pig's shy—doesn't like strangers."
That night the stronghold slaughtered three pigs; blood dyed the ravine red and every loose tongue was fed to the swine.
Two-Dog kissed Old Black on the snout: "Good brother—more reliable than any human."
