Knot Chain

There was a knotted rope wrapped around the tree trunk outside my apartment.

This meant that the meeting I had that morning was compromised.

This meant that I went to my vantage point with my briefcase.

This meant that I was able to scope out my contact who had betrayed me.

This meant I killed them with my sniper rifle from my briefcase.

This meant I had to get out of the country asap.

This meant I had no time to destroy my records and had to rely on the timer.

This meant their plan to get my records worked.
