In Chapter Five I have a character who must appear to be a goody, but in actual fact he's working for the enemy. I want to write it in such a way that the reader won't see through the disguise on the first reading, but when (if) they read it for a second time they will learn more about how deceitful this particular character is. The problem I have when writing like this is that I always feel like I've given too much away and so constantly alter it to make things more subtle to the point that it no longer achieves its purpose.
I've adopted the mentality that as long as I'm constantly working on it, it doesn't really matter when I finish. Once the plot inconsistencies have been rectified I think that I'll feel much better about it all. So for now I'm going to get back to it and hopefully complete the editing of Chapter Five tonight.
