"The mystery of the bizarre deaths of elite Russian hikers in a 1959 tragedy on a deadly Ural mountain is the subject of Eichar's extensive investigation. (...) Possible causes for the panic, according to Eichar and officials, are: an avalanche; mysterious armed men; even a fatal tiff by the males over the women. As the elements of this complicated tangle are compiled, the final wrap-up of the mountain tragedy is overwhelming, befitting a case defying explanation.
