Lithium: the new gold. With the government's move for greener energy and the rapid growth of EV car sales, mining lithium could transform sleepy Cornwall into a new industrial power.

But when a body is found deep underground at the county's first commercial lithium mine, there's a lot at stake.

Detective Inspector Robert Rego is trying to work the case but is being frustrated at every turn. When it seems as though the answer is buried deep in the past, he turns to local officer Police Constable Tamsyn Poldhu whose family roots go back across the decades – and are deeply entwined with the new mine.
