“The Slavers,” Part 5 of 6: Frank Castle is outgunned and outmatched. He’s got his primary target in his sight—the executor of heinous crimes against young women—but a cadre of well-armed and rigorously trained bodyguards stands in his way. With deadly obstacles and shaky alliances buckling under his feet, Frank has to decide how best to dismember the slavers—does he cut off the arm or the brain of the operation first? And how big a blade should he use?
