The book of biography

John/Jenny Walker is cleaning up the house of his uncle, Gabriel, before selling it. Gabriel died in a car crash after falling from a cliff nearby. Some says it wasn't an accident, but who knows. (S)he wasn't really close, so (s)he doesn't care. The whole family have taken the whole week-end to take out everything after the funerals.

But as they are all leaving, John/Jenny misses a step in the stairs and discovers a hidden stash under one of the said steps. In it, there is a book, wrapped in a grey tissue. It seems really old and have no title. Inside, it's just white pages.

"Odd..."

John/Jenny puts back the stair in place and takes the book. Such an old item should have at least some value.

"You're coming ?"

John/Jenny's mom is on the doorstep outside, waiting for her/him, ready to leave.

"Yeah mom !"

(S)he look one last time the book and notice that, now, there is texts on it. A lot of it ! Frowning John/Jenny look closer and notice something really really weird...

It's described in excruciating details how his/her mom met his/her dad...
