Model response

The body of Lord Harrington was found in the library, with a poisoned glass carefully placed on the floor nearby. The room was cold, with shadows cast by the flickering candlelight dancing on the walls softly creating an eerie atmosphere. On the desk, a note was left, but its words were completely smudged beyond recognition and nearly illegible to anyone. Detective Marlow entered silently, his mind racing to piece together the clues before dawn broke outside the storm raged fiercely.
