Il tunnel dell'orrore

Clint Callaghan isn’t crazy. Not completely at least. His strings are pulled by an invisible puppeteer who commands him to kill without mercy or purpose. Now the army is besieging him and his life’s reached the terminus... Only Dylan Dog can help him find out what is hidden in his past, when he was an orphan. It’s a tunnel filled with shadows that the Investigator has to slip through, a tunnel of horror leading straight to an old acquaintance of his: Professor Hicks!
