The heavy rain thundered loudly against the huge and cold, dark glass windowpane outside all night long this dark morning. Silence filled the dimly lit study where the lifeless body lay perfectly still on the cold stone floor just nearby. Detective Miller stepped carefully inside the room and looked around with a very thoughtful, deep, and clearly troubled facial expression. A single, red rose sat motionless upon the polished mahogany desk directly right next to the victim's empty wooden chair. Detective Miller found no signs of a struggle inside this peaceful, and well-kept house near the end of the street. He noticed a single, muddy footprint leading towards the back door, which was left slightly ajar in the pouring rain. This discovery confirmed that someone had entered and committed a terrible crime before vanishing into the darkness of the night.
