The cold autumn rain fell softly upon the dark wet cobblestones just outside the grand mansion on Blackwood Lane tonight. Detective Arthur Pendelton slowly pushed open the rusted heavy iron gate and walked directly toward the flickering yellow porch lights. One hysterical young maid had called the police station reporting a terrible tragedy inside the study of the wealthy banker. He stepped through the massive wooden front door and immediately noticed the strangely lingering scent of expensive imported cigar smoke. In the center of the dimly lit room, a cold lifeless body lay sprawled across the large antique Persian rug. Dark crimson blood slowly pooled around the head of the victim, staining the intricate woven patterns beneath his shattered skull. Arthur knelt beside the cooling corpse and carefully examined the deep gruesome wound without disturbing any potential evidence left nearby. One heavy silver candlestick lay discarded on the wooden floor near the fireplace, covered in thick sticky dark crimson residue. However, the heavy front door had been locked from inside, making this seemingly brutal murder quite impossible to easily solve. Arthur stood up slowly and looked around the completely silent room for any hidden clues about the elusive unknown killer.
