Thank You very much to you all. I was afraid that part 2 was the less interesting part of the 3. That's the part that was the most diffcult for me to write.
I wanted to made Lois's conclusions believable, and I was afraid I failed.
Personaly, that's the part 3 I prefered. I hope that will be the same for you. I post it right now.
I'm delighted you like my story so far. I wasn't very sure that to write a story in the first person was a good idea.
