I want to say the book title is "To Catch a Spy" - but there more than one of the same title. I don't know which one to pick without checking them for, maybe, references to the Big Ben Clock Tower - or London?

I do know Mad Magazine's Spy vs. Spy guy when I see him!



And the other guy with the net is from a cartoon by Ellis Nadler, but don't know what reference there might be for it.

The last image on the bottom right looks irritatingly familiar, is it from a flash game we played early this year, maybe?
