## Synopsis (in-house rewrite)

Foghorns groan over Block Island at dusk.  
Tom Lynch’s fishing boat creaks, empty nets dragging; his daughter studies sonar blips that pulse like irregular heartbeats.  
Less *Jaws* than *The Shining* at sea—a slow leak of dread through peeling paint and strained phone calls.

**Mood tags**: dread, slow-burn
