A U.S. Nazi Spy Network Threatens the Course of WW2 Colorado, Springs,1942. After her father fails to show at their regular Tuesday meeting, Laura Atweiler discovers him close to death on Longs Peak. General Arthur Atweiler had been scouting for a new training camp location for the mountaineers of the Tenth Mountain Division of the Army. Seven are dead. The General has been tortured because of something he knows. His last words to Laura implicate high-level U.S. Army officers in his murder. Laura searches for the murderers but can trust no one. Two days later, COI agent Ian McKay shows up at her door. He seems to know more about General Atweiler than he should, certainly more than Laura knows. She cannot trust McKay, but she also cannot get rid of him. Laura learns that her father's death is related to race riots in Chicago, Los Angeles, and New York. His death also reveals sabotage in U.S. munitions and ship-building factories - all the work of Nazi sympathizers and Nazi spies led by Werner Arndt, a man her father had trusted to teach climbing techniques to the U.S. Tenth Division mountaineers. Can Laura learn the truth and trap Arndt before his network destroys U.S. morale and preparations for the war? How can she succeed when Agent McKay puts up barriers at every turn?
