As an aside, if you like graphic novels and philoshopy then I highly recommend Logicomix [1]. This work heavily features Ludwig Wittgenstein. I can't claim it is historically accurate but I do think it is quite an interesting read.
As a historical narrative it's pretty shameless, e.g. inventing out of whole cloth a second visit to Frege. I also felt that it did not convey well the personalities (let alone the ideas) of the early analytical trinity.
