Yes, perfect example, and my interest definitely stemmed from 1st person present tense narrations. Reading things like survivor or Fight Club by Palahniuk, but still having that feeling that it's all already done with (especially Survivor). The Christie example reminds me of a WiP I have on the back burner but deals with the same thing: The twist although a clear contrivance gives way to not only a feeling of freedom on the part of the narrator but also a sense of control or power. A re-reading may not yield the same results though, which is interesting to me.
