I've just noticed that if I open Disk Utility, it lists each unlocked Espionage folder together with its sparse image and allows you to reveal the location of each sparse image by ctrl-clicking it in the Disk Utility list. This is so even if Espionage itself is locked. Doesn't this undermine 'plausible deniability'?
