The world wrecker

"The strange reports came from all over the world. Reports of a bearded man who could walk through solid walls. Business conferences found a stranger listening to their secret plans; military documents and gold reserves disappeared from impregnable safes; Miss World completely vanished from a locked room before the eyes of several astonished witnesses. Cities were destroyed by gigantic earthquakes; bridges and all metal structures simply dissolved ... in fact the people of the Earth faced complete and utter destruction!"--Publisher description.
