In the dimly lit mansion the detective found the body of the wealthy heiress sprawled on the floor in silence. Blood stained the expensive carpet while the open window allowed a cold wind to howl through the empty room tonight. Suspects gathered in the parlor including the butler the gardener and the mysterious stranger who had arrived last night unexpectedly. The detective carefully examined the bloody scene noting the missing jewelry and the strange note left beside the cold body.
