Chapter 11 Knocking at The Door at Midnight(II)(12)

Master and I worked for another morning and found nothing but the half footprint. We walked to the security room at the entrance of the community, wanted to see the night’s surveillance video for luck. We were disappointed to see the videos before and after the murder, only a lot of cars coming in and out, but no suspicious person.
Master stood up, stretched out, lit a cigarette, and strolled slowly around the door of the security room.
