Blurb:”ULTIMATE WEAPON - Earth rang like a great gong. Mars roared like a gigantic brass trumpet. Venus sang with the note of a huge violin. And all of them would soon explode into lifeless asteroid belts... unless the bell from infinity stopped ringing!
The menace began in the original asteroid belt itself, where one man found what he thought was the largest diamond ever dis-covered. It was not a diamond, but a weird crystal-and it contained the bell from infin-ity. Efforts to cut it unwittingly activated it and revealed its true nature-an ultimate weapon that could reduce all planets to fragments and end lite down to the last tiny microbe.
Trapped in the airless caverns of one small asteroid, cut off from all outside help, a valiant group of Earthmen, Martians and Venusians had to unite to find the bell and put a stop to its terrible threat-although no man had ever succeeded in touching it without dying!“
