Office

Derek wore his coat and grabbed his tablet.

"Let's go." They both left the room. 

When walked out of all the door, everyone was staring at Das, but he paid no attention and kept walking forward.

Derek stopped and said, "I am going home early today. I have called 'him' for the monitoring. You guys can submit your reports and go home when you are done."

After walking straight, they reached the elevator.

"Let's go through the back exit," Das said.

Derek was confused but didn't ask the reason to Das. "Alright"

After reaching the ground floor, They took the back exits without informing the reception.

'Alright. First step is done. Now I just need to find out who are those four spies he has sent' Das had no idea who spies could be. There were dozens of employees working on each floor. It was nearly impossible for Das or anyone to identify each of them.

'Dad also forgot his phone in his office, as planned' Das smirked.
