Hidden within the derelict gardens of abandoned Wickersham Priory, a deadly secret is waiting. But when an unsuspecting young Californian named Jamie Gibson finds herself the new owner of the estate, through a surprise bequest from a total stranger---the secret begins to stir. Jamie, fired with enthusiasm to restore the gardens to their 1930s glory, seeks the help of Lawrence Kingston, a retired professor of botany, eccentric bon viveur, and amateur sleuth. Lawrence soon unearths an old chapel, which leads to an ancient Healing Well, which in turn yields a human skeleton. And as the police pursue their inquiries, Kingston begins his own investigation---following a baffling trail of clues that wind down through the centuries, from the battlegrounds of World War II to the depths of the Middle Ages.
