Leap into Darkness is a 1998 memoir by Holocaust survivor Leo Bretholz and co-author Michael Olesker, in the vein of Night by Elie Wiesel or My Brother's Voice (2003) by Stephen Nasser, in which he recounts the astounding story of his surviving the Holocaust as a young man owing to his wits, stomach for risk taking and well developed flight instinct.

His mother, more realistic than other relatives, saw disaster and insisted that he escape, which is what he did for the next seven years, traveling through Germany, Luxembourg, France and briefly, Switzerland, to jails and numerous internment camps.

In one story, he tells of a young female friend who was menaced by a gendarme while he is forced to stay hidden, "crouched on the floor, helpless, emasculated, sickened."

His flight and survival for seven years in occupied Europe spanned several countries - Austria, Germany, Luxembourg, Switzerland, Belgium and France.

Arrested and brought before an SS officer for questioning, at the railway station in Limogenes, France, while observing a transport of Jewish prisoners, Leo possessed false identification papers.
