The Mystery of the Great Pyramid, Part 2: Blake & Mortimer #3 (Adventures of Blake & Mortimer)

Captain Blake having been assassinated at Athens Airport, Olrik seems to have won the first round. A furious Mortimer swears that he'll avenge his friend. He goes on the hunt for Olrik, but information is scarce. Sheik Abdel Razek, an old man with mysterious powers, protects him against Dr. Grossgrabenstein's crew. The doctor is a devoted Egyptologist who has undertaken excavations not far from the Great Pyramid. Amidst strange events, Mortimer sometimes feels like he's losing his way in this investigation that will lead him into the darkest depths of the Great Pyramid.
