The Couple Next Door Summary & Review

What Is The Couple Next Door Book About?

Anne and Marco Conti seem like any young couple—new parents navigating sleepless nights in their upscale townhome. When neighbors Cynthia and Graham invite them to a dinner party next door, they reluctantly go, leaving baby Cora alone with a baby monitor. They take turns checking every 30 minutes.

But at 1 AM, disaster strikes: Cora’s crib is empty.

Detective Rasbach immediately suspects the parents. Why?

  • The baby monitor’s video was broken; only audio worked

  • A motion-sensor light bulb was loosened

  • Tire marks in the garage didn’t match their car

  • Anne’s postpartum depression and hazy memory

As the investigation deepens, dark truths surface:
Marco’s failing business and secret debts
Anne’s traumatic past and dissociative episodes
The Contis’ strained relationship with Anne’s wealthy, controlling parents

Evidence mounts—a hidden onesie, a ransom note, a mysterious accomplice—but nothing is as it seems. Lapena masterfully shifts suspicion between characters, making you question everyone: the anxious parents, the too-perfect neighbors, or even Anne’s powerful stepfather.
