How do you think the show handled Littlefingers Death do you think something similar will happen in the book?

While certain elements will be the same – Littlefinger getting killed by the Catspaw Dagger is thematically appropriate, Sansa being the one to uncover his lies, and maybe even Arya getting to kill the person who’s actually ultimately responsible for her family’s misfortunes – I think GRRM will execute far more deftly.
