The Major Incident Room in Chelmsford had developed its own unique, grim atmosphere. It smelled of stale coffee, stress, and the dry, papery scent of too much paperwork. DI Miles Corbin stared at his wall of horrors, feeling the weight of five impossible cases pressing down on him. The grind was the worst part of any investigation; the endless sifting through data, the chasing of dead ends, the slow, methodical assembly of a life from the digital detritus it left behind.
The door opened and Detective Chief Superintendent Davies walked in, his face a thundercloud. "Anything, Miles?"
"We're pursuing all lines of enquiry, Frank," Miles replied, the official non-answer sounding lame even to his own ears.
"The press are running front-page stories on the 'Essex Nightmares'," Davies said, his voice tight. "They're painting us as incompetent. I had the Chief Constable on the phone for an hour this morning. He wants arrests. He wants neat, tidy cases we can close." He gestured at the web of lines Miles had drawn between the victims. "He does not want… this."
"This is the case, Frank," Miles said flatly.
"Find me proof," Davies shot back. "Find me one tangible piece of evidence that links a respectable headmaster in Colchester to a trail runner in Epping, or I'm splitting these teams up and we handle them by the book. You have until the end of the week." He didn't wait for a reply before turning and leaving.
The pressure was suffocating. Needing air, Miles drove out to Colchester to walk through one of the crime scenes himself. Arthur Pendelton's house.
The silence inside the Victorian terrace was absolute. Forensics had finished, but the house remained sealed, a perfect time capsule of a man's last days. Everything was in its place. Books on Roman history were stacked neatly on an ottoman, a half-finished crossword sat on the arm of a wingback chair, and the air smelled faintly of beeswax and old paper. It was the home of a man who lived a life of quiet, deliberate order. Miles walked into the study where the old headmaster had been killed. He saw the empty whisky glass forensics had bagged, the leather-bound volumes lining the walls. This wasn't just a victim; it was a life's work, desecrated. His eyes fell on the desk blotter. Resting next to it was a beautiful fountain pen, heavy and dark green with silver trim. An object of quality, of substance. Just like the man who had owned it.
He returned to the station well after dark, the image of that quiet, violated house burned into his mind. He found DC Harris hunched over a terminal, his face illuminated by the glow of the screen, surrounded by empty mugs.
"Guv," Harris said, his voice a low, urgent whisper. He looked utterly knackered, but his eyes were bright with a manic energy. "You need to see this. It's probably nothing… but it's something."
Miles leaned over his shoulder. The screen was filled with spreadsheets of financial records. "I've been cross-referencing high-value, non-essential purchases across all five vics for the last two years," Harris explained. "It's been a black hole. They use different banks, shop at different places… except for this."
He clicked a new window open. It was an elegant, minimalist website for a company called 'The Veridian Scribe'.
"A pen?" Miles asked.
"Not just any pen, Guv. A bespoke fountain pen. Costs over three hundred quid. Sold exclusively from this one online shop." Harris started talking faster, pointing at lines on the screen. "I found the credit card statement on Ben Carter, the runner—he bought one six months ago. Jack Thorne, the doctor—a bank transfer for the exact amount. The parents of Alani Costa, the swimmer, bought her one for her twenty-first; found the email receipt. Chloe Sterling, the influencer? She featured it in a 'luxury workspace' post on her Instagram two years back; we found the invoice in her cloud backup."
Harris took a breath and looked up at Miles. "And Arthur Pendelton?"
"He had one on his desk," Miles finished, the memory of the dark green pen suddenly sharp and clear in his mind.
It was the thread. The one, impossible, tangible thread that tied a doctor, a swimmer, a runner, an influencer, and a headmaster together. It wasn't a weapon or a clue left at the scene. It was a purchase. An entry fee.
Miles stared at the elegant script on the website, a cold certainty solidifying in his gut. This was it. The shopfront for the showcase.
He put a hand on Harris's shoulder, his voice low and deadly serious.
"Harris… find out everything there is to know about this company. Directors, addresses, server locations. Everything."
He paused, leaning in closer until he was almost whispering.
"And for God's sake, do it from a library computer. Use a throwaway email. Don't use anything connected to our network. If The Echo is part of this group, we have to assume they can see us, too."
