He'd knock on the door very gently, but enough for Greene to hear him. Before coming in, walking to his front desk.. Giving him a odd stare, while he was still distracted. before announcing himself. "My name's Chris Charles, i'm from the Grimsborough PD. Mr. Greene, I heard from one of my colleagues that you wanted to give us some information regarding the recent crime that had occurred down at the stock market. do you happen to have any information on that, or have you've just come to give us the "Lay of the land", per say?" He'd kick back and relax, pulling up a chair that wasn't free, and sitting downwards. "And I do apologize for rudely bursting in, but time is running short here. Usually if a murder isn't solved in the first few days, that escalates the chances of it not being solved at all quite the bit. So, I do hope that you understand my hastiness here." He did seem a bit... Antsy while being around Greene, analyzing the room for anything of note besides the after-mentioned chair.
