Freida McFadden's got a particular rhythm, doesn't she? The domestic setting, the twist you sort of see coming but enjoy anyway, the relatively brisk pace. You're probably looking for that same kind of easy-digest, high-tension read. I'd steer you toward authors like Shari Lapena and Alice Feeney. Lapena's 'The Couple Next Door' is basically the blueprint for that 'neighbors with secrets' vibe, and she's reliably fast. Feeney gets a bit darker and more psychological, sometimes with an unreliable narrator that really gets under your skin, like in 'Rock Paper Scissors'.
Another one I don't see mentioned enough is Robyn Harding. Her books, like 'The Swap', often involve seemingly ordinary women making increasingly terrible decisions, and she nails that uncomfortable, 'this could happen' feeling. They aren't literary masterpieces, but they're exactly the kind of book you finish in a weekend because you can't put it down.
If you want something a tad more complex but still in that wheelhouse, try Claire McGowan. Her Paula Maguire series has a procedural element, but the character psychology is sharp and the domestic tensions are always front and center.
