Groomed: Coercion, Control and a Cold-blooded Murder
The horrifying story of Jonathan Cresswell and the rape and murder of 21 year old showjumper Katie Simpson, who was initially thought to have taken her own life until Cresswell's crime was uncovered
Jonathan Cresswell was a dangerous and violent man, particularly to women. He manipulated his many girlfriends using coercive control and physically assaulted them if they didn't do as he wished.
In August 2020 he raped and murdered showjumper Katie Simpson, the sister of his partner and the aunt of his two children. He attempted to cover up the murder and pretended he had found her hanging from the landing in their shared home, and he very nearly got away with it. Only the persistence of an investigative journalist, suspicious nurses and Katie's concerned family and friends caused the PSNI to open a case almost five months after her death.
During the resulting trial Cresswell killed himself. Three other women were charged with helping him to conceal his crime, and each received a suspended sentence due their deference of being under Cresswell's control.

Dark, Compelling, and Unforgettable
Nicola has delivered a masterfully written story that is as gripping as it is harrowing. Sadly all of this detail is true. The narrative pulls you in immediately, with meticulous detail that brings both the setting and the characters vividly to life. Her depiction of cult manipulation, psychological control, and the tragic consequences of unchecked power is chilling, yet handled with intelligence and sensitivity.
What makes this book particularly compelling is how it intertwines personal, local experiences with larger societal failures. The story doesn’t just shock — it makes you think, reflecting on accountability, the courage of those who speak out, and the lingering effects of corruption and indifference.
The audiobook narration is flawless by Talant, allowing every tense, emotional moment to land with impact. This is a book that stays with you long after the last chapter — a dark, unforgettable story told with brilliance and precision.

Very interesting once I worked my way around the unnecessary aspects.
I nearly stopped reading but persevered and about a third of the way in this horrifying story gains traction and relevance. Coercive control, grooming, domestic violence and abuse are factually delivered in a case that so nearly went the way of the accused.
What a horrifying end for someone so young.

I was first aware of Nicola after listening to her true crime story, The witness . This was an incredible account of a boy’s astonishing bravery after being groomed by a drug dealer. I had high hopes for this one too, but I found it too drawn out. I felt the whole story could have been covered over 2 to 3 hours. 3 and a half stars

Nicola Tallant’s Groomed is a stark, unflinching account of coercive control and institutional failure, told with a journalistic clarity that makes its horrors all the more chilling. The book traces the manipulation and abuse perpetrated by Jonathan Creswell, culminating in the rape and murder of 21-year-old Katie Simpson, a crime initially dismissed as suicide by the Northern Irish police.
The author's style is deliberately straightforward, almost clinical, and that restraint becomes its own kind of indictment. She doesn’t dramatise the violence; instead, she lays out the facts with a quiet precision that forces the reader to sit with the discomfort. It’s this tonal discipline that makes the story so devastating. There’s no narrative flourish to soften the blow—just the brutal reality of a young woman groomed, isolated, and ultimately killed.
What’s most disturbing is not just the crime itself, but the systemic apathy that allowed it to happen. The PSNI’s repeated failure to act on clear warning signs—despite medical professionals raising alarms and journalists uncovering patterns—feels like a betrayal of public trust. Nicola Tallant doesn’t just tell Katie’s story; she exposes the machinery of silence and complicity that let Creswell operate unchecked.
Groomed is not an easy read, but it’s an essential one. It demands that we look beyond the sensational headlines and ask harder questions about power, protection, and accountability. The author's restraint is her strength, and in that quiet, she gives voice to the victims who were never heard.

This is the true story of Jonathon Cresswell who was a dangerous and violent man, particularly to women. He manipulated his many girlfriends using coercive control and physically assaulted them if they didn't do as they were told. In August 2020 he raped and murdered showjumper Katie Simpson, the sister of his partner and aunt to his two children. He attempted to cover up the murder and pretened he found her hanging from the landing in their shared home, and he nearly got away with it. Only the persistence of an investigative journalist, suspicious nurses, and Katie's concerned family and friends caused the PSNI to open a case almost five months after her death.
As you can imagine, this was quite a harrowing book to read. Jonathon Cresswell was a despicable human. He liked to control and physically assault women. His poor children are going to grow up knowing that their father killed their aunt. They could even be bullied over it. Cresswell took the coward's way out and killed himself during the trial. This book won't be for everyone due to its contents.

This book was heavy.
It tells the horrifying true story of Jonathan Cresswell and the rape and murder of Katie Simpson, a 21-year-old show jumper whose death was initially ruled a suicide. It’s an absolutely heartbreaking story about manipulation, coercive control, and the failures that let someone like Cresswell almost get away with such a horrific crime.
I’ll give the author full credit, it’s well written, well researched, and hits hard in all the right ways. You can tell a lot of work went into making sure Katie’s story was told with care. That said… it was a bit of a struggle bus at times. The amount of repetition and random background info (that felt more like a history lecture) really slowed things down for me and at one point I won’t lie, I may or may not have skimmed a few pages here or there. I found myself wishing the focus had stayed tighter on Katie and the investigation because that’s honestly where the story was strongest.
However, once you strip back the filler, though, this is a powerful and important read that shines a light on coercive control and justice for victims of abuse. It’s not an easy book to read, so please bear this in mind when picking up this read.
