Vacation—the very word has been foreign to Episcopal priest Tim Kavanagh. Now retired from tending his flock in the village of Mitford, he is making good on a promise to show his wife, Cynthia, the charming land of his Irish ancestors. But after arriving at a Lough Arrow fishing lodge in the midst of a torrential downpour, the charm disappears. They find their holiday upended by an intruder, a treasured painting is stolen from the lodge, and a family conflict dating back nearly a century turns even more bitter. As three generations struggle to find deliverance from the crucifying power of secrets, Tim and Cynthia stumble upon a faded journal that might just explain the crime—and offer a chance at redemption.
