Anne and Marco are parents to a six month old baby girl named Cora. One night Anne and Marco are invited next door to Cynthia’s townhome for a birthday dinner, but Cynthia does not want any children over because Cora is a fussy baby. Anne and Marco’s babysitter cancels on them, which leads them to leaving Cora home alone in their townhouse. Since they would be over in the townhouse next to them, they would use their baby monitor and take turns every half an hour to check on Cora. When they return to their home at 1:30 AM, they notice the front door is open and that Cora is missing. This leads to Anne calling the police.
The Couple Next Door is told in multiple perspectives with a ton of secrets, manipulation, and a representation of mental illness.
I really enjoyed the twists and turns of the story with the constant guessing of who kidnapped Cora. The ending was satisfying and something I was not expecting.
