This seems like an interesting concept for a thriller. I’m a little confused at the moment as to what the real problem/situation is. The blurb indicates the nanny goes missing so it’s a question of whether Martha/Anne is the one behind it or the sleazy husband, or even the nanny herself. The texts from Anne indicate 2 women are in cahoots. Seems like this would be a twist upon twist kind of tale - similar to girl on the train.
