The bullet hole in front of Kieran was enough to let him know what was going on. He knew perfectly well what would happen to him if he stayed in the same place.
It was a sniper.
The sniper must have followed the two of them to the safe house entrance.
Maybe they had been there before Kieran and Larry had arrived, but in Kieran’s opinion, that was not likely.
If the sniper had been at the site waiting for their target to get there, they would have fired when Kieran and Larry had still been heading towards the entrance of the safe house, and not have waited for Kieran to come out of it.
There had been no obstacles on the way to the safe house, so the sniper would have had a clear line of fire. However, Kieran’s Intuition would have alerted him if he’d been under someone’s sniper scope. That previous shot had been proof enough of that. If someone had been following them, Kieran would have known.
That only left one explanation then.
I'm still a little hungover from the previous dungeon :(
