In the latest episode of Writing Wrongs, hosts Professor Tim Grant and Dr Nicci MacLeod interview Dr Isobelle Clarke to unravel a case where forensic linguistics helped track down and convict a dangerous individual.
Episode three, Imposters Tending to the Wild with Dr Isobelle Clarke, dives into the chilling case of Nikolaos Karvounakis, a self-proclaimed anarchist who planted a viable explosive device in Princes Street Gardens, Edinburgh, in 2018.
Karvounakis, a Greek national, evaded capture for years, hiding behind online anonymity and extremist rhetoric. However, forensic linguists stepped in to analyse his anonymous blog posts, revealing patterns in his language that ultimately helped Police Scotland link him to the crime. The case not only demonstrates how linguistic evidence can be a powerful forensic tool but also raises crucial questions about the role of language analysis in modern terrorism investigations.
On 11 January 2018, a suspicious cardboard box was discovered in a public seating area in Edinburgh’s Princes Street Gardens. After a controlled explosion, investigators determined the device could have caused serious harm had it detonated. With no immediate leads, the investigation stalled - until an anonymous blog post surfaced, claiming responsibility for the attack.
The post, written in both English and Spanish, was linked to an eco-anarchist group called Individualists Tending to the Wild, a Mexican-based extremist organisation advocating violent action against technological progress. Crucially, the post included an image of the bomb’s interior, a detail only the perpetrator or law enforcement could have known.
Police Scotland sought the expertise of Professor Tim Grant, who analysed the text, producing a linguistic profile that suggested the writer was neither a native English nor Spanish speaker - but rather someone influenced by another language entirely.
Two years later, police identified Nikolaos Karvounakis as a suspect. Using comparative authorship analysis, Professor Tim Grant compared his online writings - including song lyrics from his rock band - to the manifesto. By dissecting word patterns, grammatical structures and stylistic quirks, he established that Karvounakis was the likely author. This evidence -alongside forensic meteorology, which linked photos of clouds in Karvounakis’ blog posts to the same weather conditions on the day of the crime - was used to secure a warrant and seize computers containing known writings by Karvounakis.
To eliminate inevitable bias that would result from having worked the case for more than two years, Professor Grant invited Dr Isabelle Clarke onto the case as an independent forensic linguist. Using a version of the General Imposters Method, a technique similar to a police lineup but for language, Dr Clarke confirmed that the writing style in the blog post was the closest to Karvounakis’ known writings.
Police Scotland put the evidence in the case, including the linguistic evidence, to Karvounakis, and secured a guilty plea. In February 2022, Nikolaos Karvounakis was sentenced to over eight years in prison under the UK’s Terrorism Act.
Tim Grant, professor of forensic linguistics at Aston University, said:
“The case highlights the growing importance of forensic linguistics in solving crimes, particularly in an age where digital anonymity combines with extremist ideologies.
“It also highlights the how different types of language analysis can assist as a case moves through different stages of investigation.”
Dr Nicci MacLeod, deputy director of the Aston Institute for Forensic Linguistics, said:
“This episode offers listeners a behind-the-scenes look at the forensic methods that expose deception, identify threats and ultimately bring criminals to justice.”
Dr Isobelle Clarke, a lecturer in security and protection science at Lancaster University and one of the first graduates from the campus-based MA Forensic Linguistics programme at Aston University, said:
“It was great to be back at Aston University talking about the Karvounakis case for the Writing Wrongs podcast.
“It’s an interesting case to highlight, as it shows how different types of language analysis can help with police investigations.”

The true crime podcast Writing Wrongs continues its exploration of language and justice with a special bonus episode featuring best-selling author and historian Kate Summerscale. Kate is an award-winning historian, journalist and best-selling author known for her meticulous research into historical true crime cases. Her book The Suspicions of Mr. Whicher won the Samuel Johnson Prize for Non-Fiction and was adapted into a major ITV drama. Her latest book, The Peep Show: The Murders at 10 Rillington Place, revisits the infamous Christie case, shedding new light on the victims’ lives, the social conditions of post-war Britain and the power of the press in shaping public perceptions of crime.
In this episode, hosts Professor Tim Grant and Dr Nicci MacLeod explore a fresh perspective on the Rillington Place murders, the wrongful execution of Timothy Evans and how forensic linguistics has helped uncover the truth in criminal cases.
Following on from the first episode of the series, which examined the Timothy Evans case and the origins of forensic linguistics, this conversation with Kate Summerscale provides fresh historical insights into one of Britain’s most infamous miscarriages of justice.
The episode revisits the horrifying crimes of John Christie, whose calculated murders led to one of the most infamous miscarriages of justice in British history. The wrongful conviction and execution of Timothy Evans cast a long shadow over the UK’s legal system and played a pivotal role in the eventual abolition of the death penalty. Through expert discussion, the episode examines how Evans’ case became a turning point for criminal justice reform.
The conversation also looks at the role of the media in shaping crime narratives. Sensationalist reporting during the Rillington Place murders fuelled public perceptions, sometimes distorting the truth in favour of dramatic storytelling. The episode draws comparisons between 1950s tabloid journalism and today’s true crime media, examining how crime reporting has evolved - and the ethical challenges it still faces.
A deeply unsettling aspect of this case is its gendered nature. The majority of John Christie's victims were vulnerable women, many facing financial and social instability. The episode delves into how structural inequalities, from the lack of legal abortion to economic dependence, made women more susceptible to predatory figures like Christie, a pattern that remains relevant in crime analysis today.
Finally, the episode scrutinises government complicity in covering up a miscarriage of justice. The Brabin Inquiry, launched in the 1960s, sought to reexamine Evans’ conviction but delivered a highly controversial conclusion, failing to fully exonerate him. The discussion highlights how political interests and legal reputation management influenced the case’s outcome, leading to Evans’ eventual posthumous pardon - but not a full legal exoneration.
Tim Grant, professor of forensic linguistics at Aston University, said:
“It was wonderful to have Kate on Writing Wrongs. “Her work challenges the traditional true crime narrative, shifting focus from the murderer to the victims and the broader social structures that allow such crimes to happen. “Her insights in this episode provide a fresh and deeply researched perspective on a case that still haunts British legal history.” Writing Wrongs is available on Spotify, Apple Podcasts and all major streaming platforms.

True crime enthusiasts and forensic linguistics fans have a gripping new podcast to add to their playlists. Writing Wrongs, an original podcast from the Aston Institute for Forensic Linguistics (AIFL) at Aston University, provides a deep dive into how forensic language analysis plays a crucial role in solving crimes and improving the delivery of justice.
Hosts Professor Tim Grant and Dr Nicci MacLeod, leading experts in forensic linguistics, explore how police interviews and linguistic evidence played a key role in one of Britain’s most infamous miscarriages of justice. Throughout the series, they’ll explore real-life cases where forensic linguistics has played a pivotal role in solving crimes, joined by expert guests who reveal the fascinating - and sometimes chilling - ways language can expose the truth.
The first episode, Timothy Evans: A Case for Forensic Linguistics, launched on 7 March 2025, 75 years after Timothy Evans’ wrongful conviction and subsequent execution (9 March 1950). The Timothy Evans case was instrumental in the UK’s decision to abolish the death penalty, raising critical questions about police interviewing techniques, false confessions and linguistic analysis in legal proceedings.
In 1950, Evans was convicted and later hanged for the murder of his baby daughter, Geraldine, while his wife, Beryl Evans, was also presumed to be his victim. However, three years later, his neighbour at 10 Rillington Place, London, John ‘Reg’ Christie, a former police officer, was exposed as a serial killer, responsible for at least eight murders – and almost certainly including Geraldine and Beryl Evans. Despite evidence casting doubt on Evans’ guilt, he was executed before Christie’s crimes came to light. This case was instrumental in the early development of forensic linguistics, as experts later analysed Evans’ police confessions to expose inconsistencies.
Tim Grant, professor of forensic linguistics at Aston University, said:
“We are delighted to launch Writing Wrongs with this episode focussing on the wrongful conviction and execution of Timothy Evans. This episode clearly shows how language analysis can provide evidence to help resolve one of the most controversial cases in British legal history. “In other episodes we show how contemporary forensic linguists are making contributions to the delivery of justice in cases of murder, rape and terrorism. In each case we discuss with a linguist how they assisted, and demonstrate how providing linguistic evidence to the courts can exonerate or incriminate and change the outcome of cases.” Dr Nicci MacLeod, deputy director of the Aston Institute for Forensic Linguistics, said:
“This is the origin story for forensic linguistics, a phrase first coined by Jan Svartvik in his 1968 publication analysing the Evans statements. “Svartvik was able to show that there were clear differences in the language style of the incriminating sections of Evans’ ‘confession’, and other parts of the statements he gave to police. “One feature Svartvik focused on was the use of the word ‘then’ positioned after the subject of a clause, as in “I then came upstairs”, as opposed to what we might consider the more usual ordering of “then I came upstairs”. This is a feature of ‘policespeak’, and was also identified in the infamous Derek Bentley confession by Malcolm Coulthard some years later.” The first three episodes of the eight-part series of Writing Wrongs are available now on Spotify, Apple Podcasts and all major podcast platforms. They include a bonus episode with the author, Kate Summerscale ('The Suspicions of Mr Whicher' and 'The Queen of Whale Cay'), about her latest book ‘The Peepshow: The Murders at 10 Rillington Place’ and an episode featuring Dr Isobelle Clarke, which shows how a series of forensic authorship analyses assisted in the investigation and conviction of a terrorist who planted a pipe bomb in Edinburgh in 2018.
