In late spring of 1865, as America mourns the death of its leader, Washington, D.C., police detective Temple McFadden makes a startling discovery. Strapped to the body of a dead man at the B&O Railroad station are two diaries, two documents that together reveal the true depth of the Lincoln conspiracy. Securing the diaries will put Temple’s life in jeopardy—and will endanger the fragile peace of a nation still torn by war.
Temple’s quest to bring the conspirators to justice takes him on a perilous journey through the gaslit streets of the Civil War–era capital, into bawdy houses and back alleys where ruthless enemies await him in every shadowed corner. Aided by an underground network of friends—and by his wife, Fiona, a nurse who possesses a formidable arsenal of medicinal potions—Temple must stay one step ahead of Lafayette Baker, head of the Union Army’s spy service. Along the way, he’ll run from or rely on Edwin Stanton, Lincoln’s fearsome secretary of war; the legendary Scottish spymaster Allan Pinkerton; abolitionist Sojourner Truth; the photographer Alexander Gardner; and many others.
