Jake hit the pavement hard, boots skidding as he burst out of the service alley and into the open walkway. Mercer was already twenty metres ahead, weaving through the morning crowds with the precision of a man who had spent his life studying human movement. He didn’t shove anyone. He didn’t draw attention. He slipped through gaps that shouldn’t have existed.
Jake sprinted after him, breath sharp in the cold air. “Emma, he’s heading east toward the market!”
Static crackled, then Emma’s voice came through, breathless but controlled. “Shooter’s gone. The rooftop access point was forced. Professional job. I’m rerouting to you.”
Jake dodged a cyclist, vaulted a low barrier, and kept running. Mercer cut across the road, narrowly avoiding a taxi whose horn blared in protest. He didn’t look back. Not once.
That was what unsettled Jake the most.
Mercer always looked back.
Jake pushed harder.
Southbank blurred into a smear of colour — cafés, buskers, joggers, the river glinting like dull metal beside him. Mercer darted down a side street, then another, moving with the confidence of someone who had memorised every blind spot in the city.
Jake followed him into a narrow lane lined with brick walls and delivery doors. The noise of the river faded behind them, replaced by the echo of footsteps and Jake’s own heartbeat.
Mercer glanced over his shoulder for the first time.
Not to check his tail.
To check the rooftops.
Jake saw the fear in his eyes.
This wasn’t a man running from MI5.
This was a man running for his life.
“Mercer!” Jake shouted. “Stop! We can protect you!”
Mercer didn’t slow. “You can’t protect yourselves!”
He turned sharply into a wider street — and that was his mistake.
Borough Market was waking up. Vendors were setting up stalls, crates of produce stacked high, the air thick with the smell of bread and early‑morning coffee. It was busy enough to hide in, but not busy enough to disappear completely.
Jake closed the distance.
Mercer darted behind a stack of vegetable crates.
Jake lunged.
They collided, crashing into the crates, sending oranges rolling across the cobblestones. Mercer struggled, but exhaustion and panic had dulled his edge. Jake pinned him with a forearm across the chest.
“Stop fighting!” Jake snapped. “We’re not your enemy!”
Mercer froze, chest heaving. His eyes darted around the market, scanning rooftops, windows, and shadows.
“They’re coming,” he whispered. “You don’t understand. They won’t stop.”
Emma arrived seconds later, breath sharp, hair slightly dishevelled from the rooftop chase. She aimed her weapon low, ready but not threatening.
“Shooter’s gone,” she said. “Clean escape route. No trace.”
Mercer let out a bitter laugh. “Of course, there’s no trace. They’re ghosts. Off‑books. They answer to one person.”
Jake tightened his grip. “Who?”
Mercer swallowed hard. “The leak inside MI5.”
Emma’s jaw clenched. “You’re saying someone in the Directorate ordered the hit?”
Mercer nodded. “And they’ll keep sending people until I’m dead.”
Jake eased off him slightly. “Then you’re coming with us. Safehouse. Now.”
Mercer didn’t resist this time. He looked defeated. Hollow. But beneath the exhaustion, Jake saw something else — determination. Mercer wasn’t just running.
He was trying to survive long enough to tell them something.
Emma holstered her weapon. “Let’s move before the market fills up.”
Jake pulled Mercer to his feet. “You’re going to explain everything.”
Mercer met his eyes. “I will. But you need to understand something first.”
Jake frowned. “What?”
Mercer’s voice dropped to a whisper.
“Operation Captura isn’t about capturing me. It’s about capturing the truth.”
Jake felt a chill run through him.
Emma stepped closer. “Then let’s start with the part where someone tried to kill you.”
Mercer nodded slowly. “Fine. But once I tell you… There’s no going back.”
Jake exchanged a look with Emma.
They already knew that.
