The Secret Spy Message

We know that our main character is trying to get his secret spy message out. So because of the contrivance that Sun happened to over here, this bust up across the phone line, he now has an opportunity to do one big grand act before he's captured. And the rest of the story then deviate. We are not given what his plan is. Only that he said in a matter of about 10 minutes or so I formulated the plan. It's well written, but it's also like not in the wheelhouse we would expect of Borges. But as he is traveling, we do get this interesting paragraph that becomes really important to understanding his motivation for the end of the story
