Unfortunately I don't have as much knowledge of saint-just and camille as I would like; all my time has been taken up with Robespierre, just cos, obviously XDD

But have a flick through/read some of the chapters of Hilary mantel's A place of greater safety (it's a fantastically written book although I know maelicia doesn't approve XDD - I haven't yet got to any saint-just bits, so I don't know how incorrect her interpretation of him will be). It's great for characterisation of camille. Have fun, good luck. :P
