A skeleton buried on a lonely Northumberland hill?

Nothing wrong with that. Garrigill was once an ancient burial ground.

Archaeologist Rena Williams is here to excavate the site. She is an old friend of Arnold’s. And with his help, her team have uncovered more than a few old bones already.

But never like this.

The bludgeoned skull, the modern dental work … nothing about this death feels accidental. Or even all that old.

Who was the dead man, and what did he know that was worth killing for?

Arnold’s determined to get to the bottom of it all, but then one of his hotheaded young teammates turns up dead in a ditch.

What if someone now wants Arnold dead?
