Model response

The wealthy lord was found brutally murdered in his isolated countryside estate late during a very stormy and ominous evening. Several guests who were staying at the mansion became immediate suspects due to their recent arguments with the deceased nobleman. The seasoned detective began to carefully examine the crime scene looking for any hidden evidence that might identify the murderer. The butler seemed nervous as the detective questioned him about his precise location at the time when the murder occurred.
