It may rival the length in Part 3, but not sure. It is bigger than Part 1 at this instant, and around the same size as Part 2. But, I am not finished this Part 4 yet, so it could be bigger than Part 2, or even Part 3.
I have still around 2 scenes to complete, but sometimes on scene can grow into a little more action, or humor in between, as what has happened today.
Then when editing the material, it should grow a little more again ( more descriptive writings, and putting in some things that I may have left out), usually calls for the main body to grow as well.
I am at around 52 000 words now. We will see how the rest goes.
Till next time.
