In too steep

It seemed like a simple case: the murder of Lewis Trenton, a beachcomber who lived alone in a cabin in the Oregon hills. But the newspaper article piques the interest of Vivian Wainwright, owner of the British-style Misty Bay Tearoom. The photo accompanying the article shows Lewis's cluttered living room, and on the shelf is a replica of Big Ben. Vivian is sure she sold the clock a week before in her shop. Who could have given the replica to Lewis?
