"On the Road to the Wolf's Lair: German Resistance to Hitler"
by Theodore S. Hamerow
http://www.amazon.com/exec/obidos/ASIN/0674636813/wendysmallThough written as a historical account, "On the Road to the
Wolf's Lair" reads at times like a spy thriller, complete
with intrigue and danger. It is also meticulously
researched, offering insight into the rise and fall of the
Third Reich from the perspective of German resisters who
once supported the movement. Theodore S. Hamerow closely
examines why these people chose not only to reverse their
alliance in spirit but to take active steps to overthrow the
regime, which culminated in an unsuccessful attempt to
assassinate Hitler at his headquarters--the
"Wolf's Lair"--in East Prussia in 1944.
