The old mansion stood silent under the heavy rain clouds. A body lay sprawled across the cold white marble floor. Thick blood stained the expensive Persian rug beneath the victim. The shocked butler discovered the gruesome scene early this morning. Police sirens wailed loudly as they approached the estate gates. Detective Harris examined the bloody evidence with careful professional eyes.
