Un vampiro a New York
In New York, a mysterious murderer is raging who sucks the blood of his victims (like a vampire) and then kills them, using a knife with a wooden blade. Inspector Travis, who leads the investigation, asks Martin Mystère for help and, together, they discover one of the killer's hideouts... The circle tightens around Herman Strauss, the Dagger Assassin, or the mysterious serial killer who terrorizes New York. Mystère will find herself face to face with the person who embodies one of the fundamental figures of horror fiction: an authentic vampire. But Herman Strauss is not a simple "monster"; he is a man, victim of a curse, who experiences his condition with desperation and anguish. An unsustainable condition that will, in the end, find a dramatic epilogue.
