I spent nearly a decade fighting to free my mother. Today I help organisations understand coercive control, the impact of domestic abuse on children, and men’s responsibility to challenge misogyny and violence against women.
Long before the unthinkable, coercive control had shaped my family for decades.
My parents were together for more than forty years. Control shaped my mother Sally’s life and the home my brother and I grew up in. In August 2010, she killed my father. The following morning, she drove me to work, told me she loved me and then drove to Beachy Head, where she tried to end her life.
Sally was portrayed as a jealous woman who had killed her husband. The fear and control we had witnessed were not placed in the context of the life she had lived with my father. My brother James and I began speaking about the story the case had left out.
Together, we led the campaign to make visible what the justice system had failed to see. In 2019, the Court of Appeal quashed her murder conviction. The fight also forced me to return to my own childhood and recognise what children absorb before they have words to name it.
01 / The story
The fight to free my mother began with my brother James and me unearthing the life she had lived before the killing: the control, fear and silences we had witnessed growing up, and which the first trial had failed to see.
Following her story back into the home where we grew up meant confronting my own childhood, and recognising what children absorb long before they have words for abuse.
Before
From the outside, ours looked like an ordinary family. Inside, the home was organised around my father’s moods, entitlement and control. As a child I felt the atmosphere long before I could explain it.
Watch / BBC
This BBC film follows our family through the appeal and into the history the first trial failed to see. It places the public campaign inside the private experience of being a son.
What the appeal changed
My mother was 15 when she met my father, who was 21. By the time of the killing, they had spent more than four decades together. Yet at her 2011 trial, the case focused largely on the later years of their relationship. Her state of mind was explained primarily through depression, while the much longer pattern of isolation, humiliation, sexual violence and control remained without its proper context.
The appeal did not excuse the killing. Fresh psychiatric evidence undermined the safety of the murder conviction and brought before the court a fuller account of the life and abusive relationship that had preceded it.

02 / Coercive control
Coercive control is a repeated pattern that strips away another person’s freedom and sense of self. Any single act can look trivial from outside. Its meaning lies in the repetition, the context and the fear of what follows.
Contact, movement, money and everyday decisions are steadily restricted. A person’s world becomes smaller as the controlling person’s authority expands; confidence, autonomy and sense of self begin to erode.
Ordinary choices become things to explain, justify or seek permission for. The pattern reaches into time, messages, clothing, work, friendships and family life.
Humiliation, silence, intimidation, deprivation, threats or violence teach everyone what resistance may cost. The response may change, but the purpose is control.
People learn to monitor moods, calculate risk and change their behaviour before anything is said. Control begins to organise the home through anticipation.
These tactics do not follow a fixed sequence. They overlap, adapt and intensify. What matters is their cumulative effect: one person taking away another’s freedom, autonomy and capacity to act.
Inside the home
Coercion changes where people can speak, rest, connect, spend, leave or feel safe. Ordinary spaces begin to carry the meaning of the control exercised within them.
Children are tuning forks in the home. They feel the tension, silence and fear long before they can name it. They are not outside the abuse; they live inside its atmosphere.
Cooking, cleaning, shopping and keeping family life moving stop being ordinary acts of care. They become expectations to meet, standards to be judged against, and another way control is enforced.
Who chooses what is watched, who gets to speak, where people sit and when conversation ends can all begin to revolve around one person’s moods and preferences. Even rest and togetherness become shaped by control.
Friends and family are treated as threats to the relationship. Invitations become difficult, contact shrinks, and as outside relationships fall away, the controlling person’s influence grows.

Selected media
Across broadcast, print and international media, I use one family’s story to make the wider patterns of coercive control, justice and children’s experiences visible.
Published commentary
Commentary grounded in lived experience and campaigning, examining how abuse is understood, where responsibility sits, and the institutions and cultures that allow it to continue.
The bestselling memoir
I thought I was writing the story of how I fought to free my mother. I was also confronting the home that had shaped me.
A memoir with the pace and emotional force of a novel, The Unthinkable follows a son back through his family’s past to understand the act that shattered it, and the coercive control that had shaped their home long before.
The Unthinkable / In their words
“David is one of the most courageous men I know… everyone should read this to understand coercive control and what it is like for a child growing up with domestic abuse.”
Melanie Brown MBE
“Unthinkable stares down horror and heartbreak. A story told with unflinching courage and a compelling drive for the truth.”
Laura Kuenssberg
“Beautifully written and deeply moving… a powerful call to action as much as a very personal memoir.”
