Espionage. Impersonation. Thrills. When Lady Stapleton from England, accompanied by son Cedric, meets her cousin Harriet at Richmond after thirty years, little does the latter know that the two are imposters. At the behest of ace detective Allan Pinkerton, alias Major E. J. Allen of the Union Army, they are on a daring spying mission behind enemy lines to collect vital secrets of a new weapon project of the confederates, under special orders from President Abraham Lincoln. Under constant surveillance by the Confederate Army and surrounded by ever-lurking danger, the spy team goes about their task with meticulous planning. Will they succeed and survive? Or will the double-dealing and the machinations get the better of them? A crackerjack, edge-of-the-seat espionage thriller set against the upheaval of the American Civil War.
