Adventures of Blake and Mortimer, Paperback/Yves Sente

A Soviet rocket falls back to Earth carrying deadly bacteria. KGB Professor Voronov turns the extraterrestrial threat into a terrifying weapon that could be used to devastate the Western world-but he doesn't take into account the vigilance of Her Majesty's intelligence services. Soon, Blake and Mortimer are drawn into a lethal, shadowy war, from Moscow to London, where the stakes are no less than international peace and the real enemy may not be so obvious.
