-- Bath, England, 1891.William entreats Lady Amy Lovell, a fellow member of the Mystery Book Club of Bath, to help him deduce what really happened to the late Mr. Harding. Lady Amy, a celebrated mystery author herself, once called on William to help her solve a real-life mystery, and now she fully intends to return the favor. But it won't be easy. Practically every one of Harding's many clients had ample reason to want to do him in. And there's precious little time to narrow down the list: William and Amy soon become prime suspects themselves when the police discover them ruffling through files in Harding's house. Lady Amy will have to be as clever as her characters if she's to save William from the gallows...and herself from Harding's real killer.
