"The time will come when the Constitution and the Government will hang by a thread and will be ready to fall...but this people, the Latter-Day Saints, will step forth and save it." Thus prophesied the founding prophet of the Mormon Church. Is this prophecy on the verge of being fulfilled? Some adherents to the faith within the U.S. government think so.

Unfolding on the streets of Vienna, Munich, and Washington, D.C.; and in the confines of a prison at Guantanamo Bay, Cuba, By A Thread is a tale of truth, trust, and betrayal.
