strange interview (Robert Langdon and anyone)

I was in my car waiting for my coworker to come. We have to interrogate a professor call Robert Langdon, about a murder.

I walked over to Danny's car and asked "So whose it this time?"

Don join me for this interrogatory. I walked till him. And reply "The professor Robert Langdon" while I read the files I have in my hands.

"Whose this Robert Langdon, Never heard of him before."

"Same for me. But I think he is a teacher in Nikki's high school" I simply reply, while I enter in the school follow by Don.

"Ok then lets go." I said while getting into the car.

I continue to read the files of this man fastly while we were walking in the hall of the high school "So name's Robert Langdon, 41, professor, speciality is religious iconology and symbology." I stopped and add looking at Don "Since when high school student learn these stuff?"

"Sounds like he came from Harvard."

"I can say same" I replied. And check again the paper and added "Yes he did, but why did he chose to come here for teach?" I asked while we enter in the "reception" office. A woman was standing and looking on us.

"Beats me." I said while walking in to the building.

I laugh a bit, and as the woman was still looking at us, I get my badge out and show her. "Detective Messer" and as I look at Don then to the woman "And Detective Flack". I get back my badge in my belt and then added "We want to see Professor Langdon ? Is he there right now?"

The woman said "You're in luck, he is still in his office, he will be returning to Harvard today a 8."

"Thank you." I said then I headed to Roberts office.

I thanks too, and follow Don in Roberts office. "Weird that he wants to leave us so quickly" I said to him before we find Robert.

I read the file then said "Not so weird, he scheduled it since last month, he only supposed here for a month."

"Yes, maybe he is just a substitute to another teacher" We found him and did again the introduction. "Professor Robert Langdon?" I asked for be sure of his identity. And he turn to look at us.

"Yes, and how may I help you?"

"Detective Messer and Detective Flack" I replied to him showing my badge same time Don did it.

"So why do you need me?"

"Where were you friday at 10pm?" I asked.

"I was here in the office, packing my things for my return to Harvard."

I look at Don, who was ready to say something.

"Can anyone verify that, Mr. Langdon, or do have to just trust you?"

"Yes, the camera in the hall, I think, it should prove I didnt leave this room."

"Do you know this man?" I asked while I show him a picture of the teenage who was kill.
