Detective John Smith sat at his desk, staring at the pile of paperwork in front of him. Another case, another day. Just as he was about to start going through the reports, his phone rang. It was the captain.

"Smith, we have a murder on our hands. Get down to the docks as soon as you can."

Detective Smith grabbed his coat and headed out the door. When he arrived at the scene, the dock was swarming with police officers and forensic technicians. The victim, a local businessman, had been found dead in his office.

Smith quickly scanned the scene, noting the broken window and signs of a struggle. He talked to the witnesses and gathered evidence, trying to piece together what had happened.

As he was about to leave, he noticed a small, shiny object on the floor. It was a key, and it looked like it belonged to a safety deposit box. Smith pocketed the key and headed to the bank to see what it unlocked.

Inside the box, he found a stack of cash and a note with a name and address on it. The name was that of a well-known criminal in the area.

Smith immediately went to the man's house and arrested him. The criminal eventually admitted to killing the businessman, who he claimed had double-crossed him in a deal gone bad.

With the killer in custody and the evidence to back it up, Smith closed the case and headed back to the station. Another day, another case solved.
