He looked at her. "I am giving you the chance. It is not blackmail. It is simply facts. You are not to be here. I am to be here. I give you the option of a viable legal excuse to be here. Otherwise I get you out of my way whilest I do my job. There is no blackmail in stating facts." He said with a huff. He just looked at her as she said she wanted to beat the crap out of him. "Join the crowd dear lady. I don't really care what other people think about me. I do my job and I do it well. That is all that is really important." He merely nodded his head as she continued. "Good. Now that you are on board watson we can further investigate the entire house." He said simply. He looked at her when she said she wouldn't give it and was sarcastic. "Excuse me but the first time I asked for it you completely ignored my nice asking. I did not deem it necessary to repeat a failed project."<br/><br/>He nodded his head. "Alright watson." He said simply. Investigating the pen. Turning it in all directions. E? Seemed like someone tore off the rest of the pen or it exploded off. He sniffed the pen. Smelled a bit like gunpowder. Now why would someone have gun powder in a pen? Or perhaps it was on the culprits fingers...hmmm...He looked at her and shook his head. "Why it is quite obvious dear watson. This pen is not your sisters nor is it the polices. Pens like this one are only found in the illegal parts of the city. This pen was at one point a laser flashlight. Possibly installed with other aspects that would allow for silent entry and the ability to see things in the dark." He looked at the pen. "This pen was set to explode without much explosion just enough to erase all evidence. However, the letter E is still readable. This dear watson is a valuable clue." He put it in a ziploc and stuffed it into his trench coat pocket. Magnifying glass to the ground. "It'll bear further investigation later on."
