Untangling the Web: My Journey Writing the Mystery of Sea Spider

When I set out to write Sea Spider, I knew I didn’t just want to create another “whodunit.” I wanted to build a “whatisit?”—a story where the central mystery is as slippery and layered as the world of espionage itself. Today, I’d like to pull back the curtain a little and talk about the heart of the novel: the elusive, terrifying, and deeply ambiguous figure (or figures) known only as the Sea Spider.

One question I get asked most is: “Who is the Sea Spider?” And my answer is always: “What do you think?”

You see, from the very first chapter, my goal was to make you, the reader, feel exactly what Fiona Jones feels: that cold, creeping paranoia where no one is above suspicion. Is it the quiet man who fixes the printers? The charming oligarch with unlimited resources? The boss who seems a little too eager to control the narrative? I had a fantastic time weaving this web of potential betrayals, making sure every character had a shadowy corner where a secret could hide.

I wanted the identity of the Sea Spider to be more than just a name on the final page. I wanted the hunt for it to question the very nature of betrayal in the 21st century. Is a traitor just one person? Or, in our hyper-connected world, is the most dangerous threat a network—a silent, symbiotic cell working within the system it’s meant to protect? As you followed Fiona’s investigation, I hope you felt that dawning horror, that realization that the enemy might not have a single face.

This brings me to my protagonist, Fiona “Slash” Jones. I built her to be the perfect scalpel to dissect this conspiracy: brutally pragmatic, fiercely independent, and armed with a dry wit that’s her last line of defense against a crumbling world. Writing her was a joy because she refuses to see things in black and white. “Justice has sides,” she says, “depending on who has the power to claim justice.” Through her eyes, I wanted to explore the grim calculus of survival. How far would you go to expose a truth that could get you killed? Who would you sacrifice?

So, as you turned the pages, I was right there with you, watching you piece together the clues I’d planted. Did you trust Oscar Torres’s weary authority? Did you think Eleanor Vance was a victim or something more? When you got to the end, did the final pieces click into a shape you expected, or did they form a more disturbing, complex picture?

That’s the conversation I truly love. The mystery of the Sea Spider was designed to live on in your mind, in the debates and theories you have after finishing the book.

Now, I’d love to turn the tables. Who did you trust the most when you started reading, and when did that change? What was the moment that made you gasp or rethink everything?
