The wealthy businessman was found dead in his locked office this morning by his shocked distraught secretary who screamed loudly. Police investigators arrived at the crime scene promptly and began examining every possible clue for evidence of foul play carefully. No obvious signs of forced entry were discovered suggesting that the murderer must have known the victim quite personally well. A crumpled bloodstained letter found carefully on the desk provided the sole lead pointing to several possible suspects nearby immediately. The inspector pondered deeply over the mysterious circumstances while interviewing the first round of potential witnesses one after another carefully.
