"Europe," Sally began, "when I split from Case I went all around there. Had a lot of money we got for the run, anyway it looked like a lot then. Tessier-Ashpool's AI paid it out through a Swiss bank. It erased every trace we'd ever been up the well; I mean everything, like if you looked up the names we traveled under, on the JAL shuttle, they just weren't there. Case checked it all out when we were back in Tokyo, wormed his way into all kinds of data; it was like none of it ever happened. I didn't understand how it could do that, AI or not, but nobody ever really understood what happened up there, when Case rode that Chinese icebreaker through their core ice."
