Haha, I like this a lot. You really had a handle on the voice throughout the whole piece, and I like how the narrative started to rise in action.
A few grammar things: It should be “It’s an even trade”, and I would consider dropping the “however” to make it simply “It’s an even trade; I take some of theirs, but they have to live with some of mine.” That seems to flow better. Second line of the third paragraph should be “security”. You might consider making the first sentence of that paragraph “Take this chap I’m looking at currently. I know his little secret, and he’s…” and so on.
Sorry to be nitpicky. Nice work, and thanks for entering!
