Model response

Detective Alistair Finch discovered the body at precisely midnight, beneath the glowing gaslight on a lonely, deserted Baker Street corner. A single silver dagger protruded from the victim's chest, and his eyes were wide with frozen, stark surprise and terror. A crumpled note in his hand bore a single word: 'Remember,' written in elegant, looping cursive handwriting with great care. I heard a faint whistle from the alley, then a shadow detached itself from the surrounding darkness quite slowly now. The shadowy figure approached slowly, and I realized with dread that I knew the murderer's true identity all too well.
