No One Can Know: A Novel

The USA TODAY Bestseller! Three sisters, two murders, and too many secrets to count.

“A propulsive and intricate psychological thriller. . . Meticulously plotted. . . Family connections prove both their damage and their worth in this community-focused thriller.” Kirkus (starred review)

Fourteen years ago, the Palmer sisters—Emma, Juliette, and Daphne—left their home in Arden Hills and never returned. But when Emma discovers she’s pregnant and her husband loses his job, she has no option but to return to the house that she and her estranged sisters still own . . . and where their parents were murdered.

Emma has never told anyone what she saw the night her parents died, even when she became the prime suspect. But her presence in the house threatens to uncover secrets that have stayed hidden for years, and the sisters are drawn together once again. As they face their memories of the past, rivalries restart, connections are forged, and, for the first time, Emma starts to ask questions about what really happened that night.

The more Emma learns, the more riddles emerge. And Emma begins to wonder just what her siblings will do to keep the past buried, and whether she did the right thing staying quiet about what was whispered that night: “No one can know.”

This one had me pacing as I read the second half. It kept me guessing who the real culprit was.

Fourteen years ago, Randolph and Irene Palmer were murdered in their Arden Hills home. All while their three daughters were asleep in the backyard in their tree house. The police were never able to find who murdered them, but a large amount of suspicion was placed on the Palmer’s middle daughter, Emma. The other sisters, Juliette and Daphne were questioned and let go, because the police believed they had nothing to do with the murders.

Now Emma is married and living a beautiful life with her husband Nathan. Emma has never really told Nathan the entirety of her past. When Emma comes home one afternoon and finds Nathan sitting in the kitchen, she is puzzled. Nathan explains that he has lost his job and the accepted offer on their dream home has fallen through. Emma has her own shocking news as well…she’s pregnant.

Since the sisters still own the Arden Hills home, Nathan suggests that they move in there and fix up the house to sell. With no other options, Emma agrees to the plan. Emma can’t help but wonder what really happened the night of her parents murder. Did she do the right thing by protecting her sisters? Or did she shield a killer? After all, if she didn’t do it, who did?


Reluctantly returning to her home town, Emma is still plagued by all the rumors all over again. Her sisters find out that she is back in the family home, and it is making them nervous of what Emma and Nathan might find. What if they uncover some of the families darkest secrets.

No One Can Know is another twisty, thriller that will keep you guessing until the last page. I really enjoyed the pacing of the book and found it to be very entertaining. This is my third read by the author and I can't wait to read more of her work in the future!

I have also read Kate Alice Marshall’s What Lies in the Woods and Our Last Echoes. Both were 4 star reads for me.

Lots of secrets, many motives, and you may guess but you won't know the truth until the very end.

Pretty fun. I bet a talented screenwriter/showrunner could make this into an even more entertaining, twisty, can’t resist series.

Just when you think you have it figured out... another lie. Then another lie. More secrets revealed.... it was a rollercoaster. A lot of reviews complained about the pace but I enjoyed the pace. Loved the past/present narration because you learned more pieces of the story from the perspective of all involved. I thoroughly enjoyed it. It was a quick read.
