Endgame 6

The anecdote on this one is too good, so I must include it. After that last hint from a Council member in the hall, I was headed to a taxi to get on a plane.

Defcon was over, and I hadn’t finished the final step, a particularly biting sort of failure. I passed 1o57 in the hall, and raised a hand in a wave; he was going to the Paris elevators, and he waved back, but nothing more. I didn’t want to bother him for yet another hint I wasn’t going to understand.

I headed to the taxi stand, playing with my phone, checking another option or two.
That was it. The end. I’d finished, but the final flag needed to be handed to 1o57. To hell with getting to the airport 2.5 hours early – I ran back in, and waited at the elevator 1st floor.

Sure enough, 1o57 came back down. I handed him the paper with ’91RATS’ hastily scrawled.

Metric: “well, I’m sure you’re sick of this by now, but here it is.”
1o57 : “I’ll never get sick of this. This is what I live for.”

Truth be told, me too.

One last thing before I let you go:
