John Constantine: Hellblazer #4

SCRUBBING UP, PART ONE
John Constantine was missing for years—and in that time, England needed a mystical protector, a guardian at the gates. Heroically, the young man known as Tommy Willowtree stepped into the breach! This cosmically attuned mage has held evil at bay with the force of his positive white magic, unlocking a new era of peace for the citizens of London. He is a gentleman, a scholar, a clean-living, vegan acolyte of love. So naturally, John Constantine hates his effing guts. And now they have to team up. Great.
