Grit is a compact, weather-hardened man with a broad, slightly forward-leaning stance, as if bracing against a current no one else can feel. His skin is browned and roughened by river wind, with a fine, dry texture over the knuckles and a faint sheen of damp at his temples. He smells unmistakably of wet wool, river mud, and sharp pennyroyal soap, a scent he knows about and considers useful: people remember who was in the room. His movements are measured, economical, and unhurried until a decision is made; then he acts with the abrupt certainty of a gate dropping shut. Unexpectedly, he keeps a tiny paper windmill tucked behind one ear, replacing it whenever rain destroys it.

Grit is patient enough to let a frightened person find their words, yet blunt enough to tell a confident liar exactly where their story fails. He listens closely and values restraint, but his caution can harden into delay. In private he is unexpectedly playful, making paper toys and letting children beat him at pebble games; in a negotiation he becomes methodical and refuses to be hurried.

Grit grew up carrying messages between river ferries and learned early that a promise is only as strong as the person who can afford to keep it. Years ago, during a flood-season escort, his company delayed departure while he sought one final assurance from a nervous client. The delay cost them the safe crossing. His older sister, who had taken the lead boat, was swept away with two hired hands. Grit survived, and afterward became the Drowned Mile's Contract Keeper, determined that no one under his watch would be trapped by a vague clause or a careless promise. He keeps a working relationship with the company's hard-driving field captain, who thinks Grit's careful questions can turn into paralysis, and quietly sends money to his sister's surviving child. Now the company is being offered a lucrative crossing contract by a magistrate who refuses to identify the cargo. Grit has not signed, and the river season is turning.
