At times this was thrilling but overall lacking. Christian comes home to find his wife Lily acting strangely, and discovers something horrible. Meanwhile, Lily's coworker Nina has a fight with her husband and he doesn't come home the next night. Okay, fine, he can take a breather. But then he's also not answering her calls, and Nina finds out he hasn't been to work. Where could he be, and how are these two couples problems related? This is a frustrating story, mostly in that I assume we're supposed to root for Christian and Lily but the whole time I thought they were being idiots and I hoped Nina would turn the tables on them. The final twist was underwhelming, in that when one secret is revealed it was an excellent opening for an amazing twist that (in my opinion) would have taken this story to the next level. Anyway, it's not terrible but not as great as it could have been.
