4 A.M.

It was 4 A.M. Lex Hanh was driving in the deserted city of Montreal. He didn't know why he was out at 4 A.M. He knew that he wanted information. He also knew that whatever he was about to find out wouldn't help him sleep better. Yet, there he was; driving. 

It was all about a little bit of snow and a light. He was looking for human presence. 

Four hours earlier, that light was turned off which is a pretty good indication that someone was there. However, the little bit of snow is the biggest mystery. It was in a place where anyone going through would hit it and yet, it was untouched. It retained the shape that the wind gave it. 

Why was Lex really out at 4 A.M.? Snow and light? It doesn't make any sense.
