It's what I do

Dortmunder:

It's good, and it's bad. There's a guaranteed return, and that's good. But the guarantor is Amusa, and Amusa's a rookie, and that's bad. But it's an easily transportable object, and that's good. Only it's in a rotten position in the museum, 30 steps to the quickest exit, and that's bad. And the glass over the stone, that's bad too, because that's glass with metal mixed in it, bulletproof, shatterproof. But the locks don't look impossible, 3, maybe 5 tumblers. But there's no alarm system, and that's the worst, because that means no one's going to get lazy watching, knowing the alarm will pick up their mistakes. Which means the whole thing has got to be a diversion job, and that's good and that's bad, because if the diversion's too big, it'll draw pedestrians, and if the diversion's not big enough, it won't draw that watchman. Kelp:
Dortmunder, I don't know where the hell you are, or what the hell you're saying. Just tell me, will you plan the job? Dortmunder:
[pauses, then smiles]
