For those still trying to understand the crazy world of high finance, Michael Lewis is still the best guide. Not an easy read (synthetic collateralised debt obligations, anyone?), but what carries it is Lewis's cast of eccentric characters who saw the 2008 crash coming, and it's these lively pen portraits that are as intriguing as the crash itself. TL;DR: you think there's someone at the wheel? There's not - or they're drunk.
