Ettore Majorana was an Italian theoretical physicist, defined a "genius" such as Newton and Einstein by Fermi; on 25 March 1938 he disappeared under mysterious circumstances.
In this short book published in 1975, Sciascia summarizes some of the results of the investigations and hypoteses about the disappearance, ruling out the suicide theory. Recent investigations confirmed that Majorana was still alive in the '50 and lived in Venezuela.
