Newlywed Jade Westmore has finally found her forever in husband Wells, a charming, successful, and recently divorced architect—only there’s one caveat. Behind the gates of their elysian estate, hidden from street view in the caretaker’s cottage … lives Wells’ first wife, Sylvie.

Three years ago, the original Mrs. Westmore suffered an unfortunate accident—and hasn’t uttered a sound since. Not a physician, psychologist, or world-renown specialist has been able to elicit so much as a word from the silent woman … until now.

On an ordinary Tuesday while Wells was away—despite instructions to never disturb the fragile woman—Jade visited her isolated predecessor bearing a peace offering: a bouquet of white lilies. Only she wasn’t expecting Sylvie to have something for her as well: a slip of torn notebook paper with a single word scrawled in shaky black ink.

That word? Run.
