Stone and Sky

Detective Sergeant Peter Grant takes a much-needed holiday up in Scotland. And he'll need one when this is over...

And they'll need them too, because Scotland's Granite City has more than its fair share of history and mystery, myth ... and murder.

When a body is found in a bus stop, fresh from the sea, the case smells fishy from the off.

Something may be stirring beyond the bay - but there's something far stranger in the sky...
