SciFi. Man missing arm gets paid heaps to break into high security safe on moon. Read around 2003-2008. Spoiler.

I think the guy is desperate and willing to take the insane job. The object he must steal is in a high-tech impossible to break-into protected safe or bank or similar, on a deserted moon or asteroid. The missing arm (or just hand) is a plot point - (view spoiler)[he takes drugs to heighten his mind and the phantom limb he can imagine becomes something that exists in the real world, so he can reach through a wall. (hide spoiler)] I think the author wasn't an SF author so much as fun quick thrill type books. Maybe read 15, 20 years ago. Page turner, not literary.
Thanks!

Wow, shades of Manuel "Mannie" Garcia O'Kelly-Davis and
Gil Hamilton.

Karen, are you still looking for this or did you find it?

I didn't find it. Ah well!

Dunno if Karen is still around but this somewhat reminds me of Rogue in Space by Fredric Brown. Main character Crag is missing a hand, not his whole arm, and he travels to Mars rather than the moon to break into a genius scientist's compound and steal a piece of highly desirable tech. But he doesn't have the ability to materialize his missing hand and reach through walls. He does have an artificial hand he can throw as a weapon though.

Thanks Ky, I'll try that book.
