The rain pounded against the windows of the dimly lit police station as Detective Sarah Reeves pored over the case files. A call had come in earlier that evening about a suspicious individual found covered in blood near the city park, and she had been tasked with investigating the matter.

As she delved deeper into the details, a sense of unease began to creep up her spine. The victim, a young man in his mid-twenties, had been found by a jogger, his clothes soaked in a crimson stain that had yet to be explained. There were no obvious signs of injury, and the blood did not appear to be his own.

Sarah knew that solving this case would require keen observation and an ability to piece together the puzzle, a challenge she was more than ready to take on. With a deep breath, she gathered her notes and made her way to the hospital, determined to uncover the truth behind this mysterious incident.
