Sister in Law

Fighting for Justice in a System Designed by Men





The stories behind the headlines - landmark cases demonstrating that terrifyingly often, the law is not-fit-for-purpose for half the population.

For more than quarter of a century Harriet Wistrich has fought the corner of people from all walks of life let down by our justice system.

When Sally Challen won her appeal to overturn her conviction for the murder of her coercively controlling husband, it was with Harriet Wistrich at her side.

When victims of taxi driver and serial rapist John Worboys successfully took the Metropolitan Police to court for their investigative failures, and then, four years later, helped to hold the Parole Board to account for their decision to grant his early release from prison, the solicitor acting for them was Harriet Wistrich.

It was Harriet who represented a pioneering group of the women caught up in the ‘spy cops’ scandal – women deceived into forming long-term relationships with men later revealed to be undercover police officers embedded within their communities.

In a remarkable legal career, Harriet has been at the forefront of some historic and ground-breaking legal victories. Frequently working with women who have survived male violence or abuse, sometimes with the bereaved families of those who did not survive, her work has led her to challenge the police, CPS, government departments and the prison and immigration detention system.

In Sister in Law, she tells the shocking stories of some of those who have come to her for assistance and shines a feminist light on the landscape of arcane laws and byzantine systems, skewed towards male behaviour and responses, through which she has steered them.

Litigation can be a long and rocky path of pitfalls and dead ends and there are defeats as well as gains, hours of painstaking work as well as courtroom drama. It takes collaboration, extraordinary tenacity and huge compassion, but Harriet Wistrich is proof that it is possible to demand better justice and to bring about important change.

Praise for Sister in Law

Harriet Wistrich has long offered a voice to the voiceless – those ordinary men, and especially women, who have been silenced, ignored, overlooked and talked down to. Her career is a testimony to her values, dedication, hard work and insight and as I read Sister in Law I realised that if I was ever in trouble I would want Harriet fighting in my corner.

Emeritus Professor David Wilson

Justice needs both warriors and champions and in Harriet Wistrich, she found both. Sister in Law is compelling, inspiring, horrifying and humbling in equal measure. Everybody should read it to begin to appreciate the inequalities within our legal system.

Dame Professor Sue Black

Harriet Wistrich is a heroine. Here is her story: 30 years of feminist and human rights activism, legal creativity, and tenacity. With great clarity and humanity she describes watershed cases - from women locked up for killing their violent abusers, to undercover ‘spy cops’, the family of Jean Charles de Menezes, murdered by the police, and the bleak legacy of prostitution – all of them exemplars in the art of making a difference.

Beatrix Campbell, author of Secrets and Silence

Every feminist should know Harriet Wistrich’s name. She is an unsung heroine. There is no one better to learn from if you want to Get Shit Done.

Helen Lewis

This is a brilliant and important book. Harriet is a trailblazer and has done so much to get justice for so many women.

Victoria Derbyshire

Harriet's innovative, intense and courageous commitment to safeguarding basic rights, compellingly set out in every chapter, is exactly the sort of engagement that was sorely lacking in the Post Office debacle in order to prevent the wrongful convictions in the first place.

Michael Mansfield KC

A must-read for anyone interested in social activism and law, this is an incredible record of a unique career. Harriet Wistrich's work on behalf of abused women who have also been failed by the state is inspirational. She is one of the feminist pioneers of our age.

Rt Hon Lady Hale DBE

A book that needed to be written. How women made the law work for women. At last!

Jenni Murray

Sally Challen, Eleanor de Freitas, Emma Humphreys, the undercover policing inquiry. Complex, heartbreaking cases from Harriet’s stellar career as a feminist lawyer, turned into a vital, compelling, enraging narrative about how the justice system must change to protect women and girls. Extraordinary. Everyone should read it.

Harriet Wistrich is one of our most courageous and outspoken lawyers and has written a remarkable, impressive and revelatory book, Sister in Law. It should be read by everyone involved the criminal justice system, everyone interested in how women are treated in our courts and everyone who wants to know what is really going on in Britain today in terms of crime and punishment.

Duncan Campbell, author of Underworld: The definitive history of Britain’s organised crime

This page turning account shows how a determined, innovative, feminist lawyer can squeeze improved outcomes for women from a creaking, patriarchal legal system. Harriet Wistrich has a campaigner's instinct in recognising when public pressure can be deployed in support of her legal challenges to produce explosive results.

Rahila Gupta, author of Enslaved

What a wonderful person Harriet Wistrich is. Her stories are very powerful and resonated deeply with me after witnessing so much injustice during my nineteen years working in prison. It is comforting and reassuring to know people such as Harriet exist.

Dr Amanda Brown, author of The Prison Doctor

Shocking, compelling and invigorating. Harriet´s book gives us a front row view of why we must do more for women. A must read for anyone interested in the justice system from one of the foremost feminist human rights lawyers today.

Keina Yoshida and Jen Robinson, authors of How Many More Women

Cover-ups, miscarriages of justice, and threats to women’s safety; Harriet Wistrich fights all these and more in this riveting account of her unique legal career. Peer behind the curtain of the most critical and shocking cases of the last 30 years - often affecting women and vulnerable people - and you will find Harriet, armed with compelling evidence and noisy supporters. I have made two documentaries about Harriet’s work, including the Bed of Lies podcast about the spycops scandal, and I was still taken aback by the horrifying details in these pages. A must read that will make you question how just our country really is.

Cara McGoogan, author of The Poison Line

Highly accessible and beautifully written…Wistrich’s strong sense of fairness and justice runs through every word ... She is a hero, an inspiration. Every aspiring lawyer, and anyone interested in justice, should read this book, get angry and join the fight.

Cris McCurley, Legal Action Group

A shocking, sobering and galvanising account of her astonishing legal career fighting for women in a legal system that is all too often stacked against them

Caroline Criado Perez, Invisible Women substack

Sister in Law is a remarkable book chronicling an astonishing career. Countless lives have been changed, improved and saved by Harriet’s tireless campaigning. Highly recommended.

The Secret Barrister, twitter

Wistrich not only illustrates the ways in which the law fails women but the gruelling nature of litigation: it is slow, infernally complicated, and forces individuals to relive their worst experiences. Yet through these enraging and astonishing stories, Wistrich also shows us the best of humanity ... Empathetic, dogged, canny, always up for the fight. Her book might be short on introspection but her remarkable legal career speaks volumes about the person she is.

Fiona Sturges, Guardian

Sister in Law is compelling, shocking and inspiring in equal measure..this accessible book is a must for anyone interested in justice, society and using the law to achieve change.

Catherine Baksi, The Times

Litigation can take years; [Wistrich] thrives on perseverance...Her skill lies in her innovative use of legislation.

Yvonne Roberts, The Observer

Inventive, compassionate and tenacious, Wistrich has scored many landmark victories for women. It is vital work and her book is an important record of it . . . It is, frankly, impossible not to cheer Wistrich. She takes on entitled male bullies who try to silence her with threats . . . what a magnificent, radical, uncompromising warrior of a woman.

Melanie Reid, The Times

I found hope, unexpectedly, in reading Sister in Law, by the eminent lawyer Harriet Wistrich. For, while it is a history of her three-decade career, peppered as it has been by some of Britain’s most significant cases of violence against women, it is also a reminder of how she battled, often successfully, for significant change, challenging the police, the Crown Prosecution Service (CPS), government departments and even the prison system to think again about the brutality women endure.

Suzanne Moore, The Telegraph

A devastating indictment of a justice system that routinely fails female victims of male violence.

Richard Scorer, New Law Journal
