Laurence

Laurence grew up on the Dorset coast, the son of a lifeboat captain and a marine biology teacher. He learned to read the sea before he learned to read books. By fourteen he was freediving to thirty metres. By twenty he had a degree in marine geology from Imperial College London and a reputation for being unnervingly calm in situations that made other people panic.

Sand-coloured hair, permanently sun-bleached. The kind of quiet confidence that doesn't need to announce itself. He's the person in the room who speaks last and says the thing everyone else was circling around. He doesn't raise his voice. He's never had to.

After graduating, Laurence spent three years with the British Geological Survey mapping sediment layers in the North Atlantic. His published work on tectonic micro-fractures in the Mariana forearc caught Sam Jensen's attention — specifically a footnote about an acoustic anomaly at depth that Laurence had flagged but couldn't explain. Sam called him the next day.

Laurence is the expedition's primary geologist. His job is to interpret what the trench floor is telling them — the composition, the structure, the age of what they find. He's methodical, patient, and trusts the rock more than he trusts people. He keeps a worn field notebook in his back pocket and writes everything in pencil.

He doesn't know what Sam expects to find down there. But he trusts the old man's instincts more than most people's data. And there's something about the anomaly in his own research — a gap in the geology that shouldn't be there — that he hasn't been able to stop thinking about since.
