Sniffing Around

Once it was time for the lunch break, the private investigator placed his camera in the pigeonhole compartment of his car and picked up a brown delivery envelope from the backseat of his car before stepping out of the car. He walked into the company and made his way towards the cafeteria where most of the staff were heading to. He looked around the place casually as though he was trying to find someone. 

"Hello, young lady!" He greeted politely, stopping a young lady who was walking in the same direction with him. 

"Hello, sir!" She responded, looking at him curiously.

The private investigator smiled at her, "My name is Ralph. I'm a cab driver. I dropped off a young man here sometime this morning and he seems to have forgotten this parcel in my vehicle. I would love to give it back to him, but I don't know anything about him apart from the fact that this was where I dropped him," the man said with a polite smile.
