Alex Walker stepped into his office, tired but focused. He had been working on a difficult case for weeks, and he knew it was time to take a break. He sat down at his desk and took a deep breath.

"Well, Alex," he said to himself, "looks like you're finally home."

He took off his jacket and tie and loosened his collar. He then opened his laptop and started working on his case. He worked for hours, his mind racing with possibilities.

Finally, he reached a breakthrough. He had figured out who the killer was!

He smiled to himself. He knew he was on the right track.
