(The Grey Gargoyle / Balder Must Die) This book is at the same time proof that early Marvel is too stupid to justify reading all of it and too awesome to skip. The Grey Gargoyle has an amazingly dumb origin and power set, and Thor / Don Blake resorts to equally stupid contrivances to overcome him.
Paul Duval is an ordinary – one might even say mild-mannered – French research chemist. When his boss distracts him one day, he spills an abnormal mixture on his hand that turns it into stone. He soon discovers that touching anything (people included) turns that thing to stone for an hour. He’s the only one who can move around when petrified; others are immobile. Being an intelligent, rational man, Paul decides there’s only one way to use this gift: crime!
