La pista di sangue

He is the man of a thousand faces. A mysterious bandit who, thanks to his disguise skills, seems elusive. He always leaves a playing card after every theft: that's why they call him The Jack of Spades. Not even Zagor is able to withstand him. Has the King of Darkwood perhaps found an invincible enemy?

After the adventure of Hellingen's return, this is the second story to have been produced and published only in the Collana Zenith series and therefore is only included at a later time in Zagor and Chico's return journey to Darkwood (inserted between Satko and Belve! stories).
