In the dimly lit mansion overlooking the foggy town a wealthy businessman was found dead early that very cold morning. His lifeless body lay sprawled across the large ornate Persian rug with a silver dagger protruding from his chest area. The experienced detective arrived promptly at the crime scene and began examining the room for any possible hidden clues carefully. All the suspects had gathered downstairs waiting for the interrogation that would soon reveal the cold blooded killer among them.
