Hidden Foes, Or, A Fatal Miscalculation [EPUB ebook] 

Excerpt: "Nobody had heard the report of a pistol. There had been no disturbance; in fact, no audible altercation, no startling cry for help, or even a groan of sudden, terrible distress. The man lay there as motionless, nevertheless, as if felled by a thunderbolt. His life had been snuffed out like the flame of a candle by the fury of a whirlwind. Death had come upon him like a bolt from the blue. By slow degrees his face underwent a change-but it was not the change that ordinarily follows sudden death, that peaceful calm that marks the end of earthly toil and trouble. Instead, the smoothly shaven skin seemed to shrink and wither slightly over the dead nerves and lifeless muscles, and a singular slaty hue that was hardly perceptible settled around his lips and nostrils, partly dispelling the first deathly pallor. It was as if the blast from a furnace, or the searing touch of a fiery hand, had withered and parched it. He was a comparatively young man, not over thirty, and he was fashionably clad in a plaid business suit. He was lying flat on his back on the floor of the second-story corridor of a building known as the Waldmere Chambers, in the city of Madison."
