On August 21, 2018, writer Manuel Bartual and I managed to bring more than 60 people together in a park to stare at a lamppost. Absolutely nothing happened in the park. There was nothing unusual about the lamppost either. It was all part of a mystery thread on Twitter in which a seemingly real hacker was following clues she had found on a mysterious mobile phone. One of those clues consisted of some coordinates in a park. The protagonist asked Twitter users for help: she needed someone to go there that night, photograph one of the lampposts, and send her the picture so she could continue her investigation. The readers, who were following the story with fascination, did not hesitate to accept the invitation to become part of the investigation, and flocked to the darkened park.
Manuel and I were exploring the possibilities of interactivity in fiction. Although the thread was full of moments in which we asked users to help us solve puzzles, what happened in the park that night was undoubtedly the most fascinating. For the first time, we had taken interactivity off the screen and brought it into the physical world. Readers could literally step into the setting of the story and experience the mystery for themselves. We had anticipated that perhaps one or two people might show up. More than fifty did.
At the time, fictional stories were beginning to emerge on Twitter that played with the uncertainty of whether what they told was real or invented. Twitter had always been associated with information and opinion rather than fiction, so developing a suspense story through a seemingly real account felt unexpected and intriguing. Interactive fiction on social media was booming, and it even had a name: Twitterature. In June 2018, I published a thread that went viral, and won first prize at Feria del Hilo, a competition organized by Twitter itself. A few months later, Manuel and I joined forces to create a new thread – the mystery thread mentioned at the beginning of this article.
When the pandemic arrived and lockdown began, I felt an overwhelming urge to create something new on social media. I wanted to use that period of widespread boredom to offer audiences an entertaining and different experience. But I did not want to repeat the formula of fictional stories that succeeded by blurring the line between reality and fiction.
I had learned one important lesson from those experiences: people enjoyed interacting with crime stories and feeling that they were part of an investigation. So I asked myself a question: what if I explicitly turned the whole thing into a game? No ambiguity, no deception. Instead of doctored photographs pretending to be real, I would use illustrations that made it clear from the outset that we were playing a game. It would be like taking part in a board game - but with the entire Internet.
With that idea in mind, I contacted illustrator Javi de Castro and asked him to draw a crime scene containing a series of specific elements. Those elements told a story, but not in a linear way. To reconstruct it, readers had to observe, connect details, formulate hypotheses, and draw their own conclusions. In short, they had to become detectives.
The game was an overwhelming success: it accumulated millions of views and was featured by numerous media outlets across the country. Demand for new cases was so great that I decided to put everything else aside and spend lockdown creating more crime scenes.
The first volume of CrĂmenes ilustrados was published in May 2021. Since then, the project has continued to grow, now comprising three volumes, and expanded into new territories, with editions published in 14 languages. This November, it will be published by Bloomsbury as Crime Seen!
In a world where artificial intelligence is gaining ground and social media occupies an ever-growing part of our lives, I believe this kind of interactive fiction is more relevant than ever. At a time when our consumption of content is becoming increasingly fast, passive, and automated, these stories demand precisely the opposite: they ask us to observe, think, connect clues, formulate hypotheses, and make decisions. Above all, they turn fiction into a shared experience, capable of creating communities of readers who play, debate, and solve mysteries together. Perhaps the future of fiction is not only about telling new stories, but also about finding new ways to invite readers to step inside them.
