Jake Jeffords is quite happy to go on this next mission, however dangerous it might be, because it stopped the Central American firing squad from doing their duty. The Fat Man is sending him to the Schneehorn where an avid mountain climber and mathematical genius has died. Somewhere in his possession was a vital notebook with his doodles and musings on how to overcome gravity. Jeffords must get it even if it means climbing the same mountain where the man perished.
