When Dinicoeur escapes the Bastille and flees to Spain, the Musketeers charge after him, only to be ambushed. Someone is anticipating their every move. Could there be a traitor in their midst? If the Musketeers can&;t trust each other, who can they trust? It&;s &;all for one and one for all&; . . . isn&;t it?

And don&;t miss the action-packed finale, The Last Musketeer #3: Double Cross.
