I'm getting pretty close to being able to trace the call for the sidequest Cold Call Killer. However, I was wondering if it was possible to fail the trace? It seems like there is ample opportunity to miss tracing the call, especially if you don't move your cursor. I found out that you get a game over and have to retry if you miss getting to one of the ringing phones.
What happens when you fail to trace the call? Will the entire sidequest fail, or will you get another chance to trace it?
