Faridah Àbíké-Íyímídé’s The Heirs is a fun combination of family drama, mystery, and suspense. Coming out in 2026, the young-adult thriller mixes the weird family dynamics of The Umbrella Academy with the locked-room mystery of Knives Out. The story is about the rich and controversial Leontes Button, whose death at a lavish yacht celebration sends shockwaves through his carefully controlled empire.
As investigators dig for answers, long-hidden secrets are unearthed, exposing the dark ramifications of Button’s lifelong obsession with creating human perfection.# The Button Test
Leontes Button had built his reputation on a controversial belief called the “Button Method.” In his theory, greatness is a function of environment and training, not genetics whatsoever. He took in a number of gifted children and for years subjected them to unremitting pressure to turn them into world-class prodigies.
Among them are Bilal, an Olympic champion in fencing; Fola, a mathematical genius and chess master; Octavius, a talented musician; Perdita, a gifted painter; and Romeo, Button’s greatest disappointment. Along with other young people who have been shaped by Button’s experiments, including Evie Gray and Henry Xu.
When Button is found dead shortly after the tenth annual Prodigy Ball, every guest is a potential suspect.# Who Killed Leontes Button?
The biggest revelation is that Button wasn’t killed in the usual way.
Secretly fighting terminal Stage 4 cancer, Button had started thinking about his own death. He went to Octavius and begged his son to help him kill himself. But Octavius couldn’t go through with it. He called on his siblings to help.
The family get-together soon turned into a fight. Button would put down his children, dismissing their feelings and achievements. Button was violent in his reply when at last Octavius challenged him. Romeo stepped forward to protect his brother, pushing Button aside.
The confrontation was tragic. Button lost his footing and tumbled into a mounted rhino trophy on display in the room. The horn penetrated his neck, killing him instantly.
This was a horrible accident that came about from years of emotional abuse and family tension, not a premeditated murder.# Why Did the Button Children Look into the Crime?
The siblings appear to be determined to find out who killed their father. But the real reason is far more sinister.
They all saw the fatal confrontation and they know exactly what happened. Their investigation is really an effort to find someone who could take the rap if the authorities start closing in on them.
As suspicion starts to fall on a number of suspects, including Evie Gray, the brother and sister work quietly to erase the evidence. Key clues are missing, physical evidence is destroyed and many family members fudge the story to save themselves.
It was never justice, but survival. ### Adam Gray’s Fatal Error: The Startling Truth
One of the novel’s most heartbreaking secrets is about Adam Gray.
Octavius had tampered with the brakes on a car years ago. His intentions were not bad; he hoped to fix the problem himself later, and impress his father with his mechanical abilities.
To the surprise of many, Button gifted the vehicle to Adam Gray, an accomplished archer and early participant in the Button experiment.
Adam took the car out at dangerous speeds one night when he was driving late. The passengers were thrown into a panic when the brakes failed. Bilal tried to stop the vehicle with his fencing equipment but it didn’t work. The car crashed and in the chaos Adam was accidentally stabbed.
Button covered it up instead of letting the truth come out. Tampering with evidence, tampering with the scene, Adam’s death was staged to look like a drunk-driving accident. The Gray family was bought off and any serious investigation was pretty much over.# Why Should Evie Be Suspicious?
Evie is secretive and evasive throughout the story, making her the most likely suspect.
The truth is much more emotional.
Evie never recovered from the deaths of her brother Adam and girlfriend Adelina. She saw how ready Button was to bury tragedies in order to protect his reputation, and she knew he was the one who had ruined so many lives.
When Button dies, Evie thinks one of his children must be to blame. She wants to know the truth. And she starts her own investigation.
It’s not guilt that drives her. It’s grief. She’s searching for justice for the people she lost, and she’s looking to expose the corruption that surrounded the Button family.
Once she hears the whole story and genuine remorse from Bilal and Octavius, she eventually begins to let go of her anger and move forward.Does Bilal and Anwar get back together?
One of the most emotionally affecting subplots of the novel is the relationship between Bilal and Anwar.
The pair go their separate ways, and even though they still have feelings for each other, their futures appear to be headed in different directions. Back together, they begin to repair their relationship at the Prodigy Ball.
Anwar is supportive, even when faced with difficult truths about Bilal’s role in Adam’s tragic death. Finally, his loyalty and understanding convince Bilal their relationship is worth another shot.
By the end of the novel the two are reunited and begin to build a life together.# Why Henry Xu Confesses?
Henry Xu spends years watching the Button children suffer under the demands of Leontes Button.
Henry, unlike Button, actually cares about them. Over time, He is the closest thing many of the children have to a parent.
Henry watches the video footage from the hidden cameras set up around the estate and learns precisely how Button was murdered. As investigators close in on Octavius, Henry decides to intervene.
He lies and confesses to the crime to save the family.
But Henry isn’t planning on spending the rest of his life behind bars. With the aid of the wealthy Button heirs he escapes custody and goes missing, eventually seeking a quiet future with his mother in Shanghai.# What Is the Destiny of the Button Fortune?
One last shock comes from Button’s will.
For years he has been championing the idea that nurture trumps biology, but he leaves most of his fortune to Perdita, his only biological child.
The decision reveals the hypocrisy at the core of his philosophy.
Perdita will not accept the inheritance on his terms. She instead uses her position to undermine his plans and ensure the estate is distributed more equitably among her siblings.
In the end, each family member chooses a path that reflects their own wishes, not Button’s hopes.
Romeo is going to culinary school. Fola at the academy. Bilal quits the sport of competitive fencing. Octavius devotes himself to music and spends most of his fortune. Perdita devotes herself to charity work, following in her mother’s footsteps.
For the first time they start living for themselves.# The Meaning of the Sherlock Reference
The novel concludes with a witty nod to BBC’s Sherlock.
Evie eventually learns that Henry had survived and was released from prison. In an exit chat with Romeo, she mentions “The Reichenbach Fall” — an episode where Sherlock Holmes apparently dies before secretly surviving.
The comparison is intentional.
Just as Sherlock faked his death to get out of an impossible situation, Henry did the same to disappear and start fresh. And then Evie drops a line that kind of hints that she knows the truth but doesn’t say it outright.# Conclusion
At its core, The Heirs is less a whodunit than a meditation on the damage wrought by impossible expectations. There’s a story behind the mystery, of trauma, family, identity, and the effort to escape a legacy of control.
The death of Leontes Button is the springboard for the investigation, but the real heart of the novel is the survivors finally reclaiming their lives from the man who spent years defining them.
