Just because you’re paranoid, doesn’t mean they aren’t out to get you. He’d kill us if he got the chance.
Our protagonist is a Private Dick with crippling social skills and extreme paranoia. He and his team are hired by some corporate suit to listen in on a couple meeting in a crowded plaza. That’s the titular conversation that he captures with technical flair. Then he joins everything together into the full conversation and the Wham Line above appears. Decisions, decisions.
Turns out he already fled the East Coast in the past, in a similar situation. A technically difficult job, leading to a murder, precisely based on the information he gathered. Not wanting more blood on his hands, he moved out. His great rival, a gregarious salesman who knows nothing of the tech side wants to buy him out, particularly for the particulars of that old job.
This is what seems to be happening here, and he wants to avoid it again. He fails miserably to keep his hands clean (with a twist), as apparently he is being watched by an even bigger fish.
The only winning move is to continue playing the sax on a dilapidated apartment, apparently bug free.
