"Elementary, my dear Watson," Holmes replied. "Suresh was deeply in debt and stood to gain a large inheritance from Raghuram's business empire if Priya were to be eliminated. The strange letters and gifts were a ruse to throw us off his trail."

"It's my daughter, Priya," Raghuram explained. "She's been receiving strange letters and gifts, and I suspect someone is trying to harm her. The police are stumped, and I need your help to find out who's behind this."

Holmes nodded and began his investigation. He interviewed Priya and her friends, gathered evidence, and analyzed the letters and gifts. After a few hours of intense investigation, he pieced together the puzzle.
