When wine consultant Sarah McKee arrives at Belle Vue Winery, the plan is simple: locate a hidden vault, assess its contents, and go home. But nothing at Belle Vue is simple. Not the legends. Not the people. And definitely not the body lying face down in a chamber that should've stayed sealed for centuries.

There's no treasure. Only questions. And one cold, brutal fact—

Someone at the winery is a killer.

Trapped on the estate and cut off from help, Sarah must unravel a web of lies before history repeats itself.

Because the vault may be open—but the killer is closing in...fast.
