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?

Unable to keep from doing a bit of sleuthing, Vivian hunts down the replica in a local thrift shop, noticing that the base is missing, rendering it worthless, but just as Vivian is about to throw it in the trash, a sparkle catches her eye. It's a diamond, hidden away in a crevice in the clock. Vivian takes the diamond to Detective Tony Messina, who identifies it as part of a jewelry heist in Portland a month earlier. Portland police think Lewis was the fence who sold the jewels, and that he was killed after double-crossing the thieves--but Messina doesn't believe the story.

What was the true motive behind Lewis's murder? How did he come upon the diamond? And what secrets can the clock tell--before the killer strikes again?
