Kurt Gödel�s Incompleteness Theorems sent shivers through Vienna�s intellectual circles and directly challenged Ludwig Wittgenstein�s dominant philosophy. Alan Turing�s mathematical genius helped him break the Nazi Enigma Code during WWII. Though they never met, their lives strangely mirrored one another�both were brilliant, and both met with tragic ends. Here, a mysterious narrator intertwines these parallel lives into a double helix of genius and anguish, wonderfully capturing not only two radiant, fragile minds but also the zeitgeist of the era.
