I'm rather skeptical that the question requires lengthy essays to answer it.
What question?
What Dawkins thinks or says is true? - That requires to read his book.
If Dawkins' arguments are sound? - That requires a lengthy essay unless you consider his arguments a priori valid or invalid, otherwise you'll not be spared the trouble of investigating them.
If there is free will or a soul? - That requires more than a lengthy essay - philosophers have been working a while on that one.
