'I doubt the Book has too many charts and graphs,' noted Butler.
Artemis smiled. 'No, I got the specifics from Foaly, not that he knows he's sharing information.'
Butler rubbed his temples. 'Artemis. I warned you not to mess with Foaly. The decoy thing is bad enough.'
Artemis was fully aware that Foaly was tracking him and any decoys he sent out. In fact he only sent out the decoys to make Foaly dip into his funds. It was his idea of a joke.
'I didn't initiate the surveillance,' objected Artemis. 'Foaly did. I found over a dozen devices on my computers alone. All I did was reverse the spike to get into some of his shared files. Nothing classified. Well, maybe a few. Foaly's been busy since he left the LEP.'
