Maid to Murder — Kate Kingsbury

WELCOME TO THE PENNYFOOT
The London aristocracy has discovered the pleasures of seaside holidays in Badgers End, and it's Cecily Sinclair's job as the owner of the Pennyfoot Hotel to keep them comfortable and entertained. Detective work is not part of her duties--but Cecily is only too willing to help the local constable when death pays an unexpected visit...

It was the oddest thing. The young maid was discovered dead in the bath with a stocking tied around her neck--and one shoe missing! And when a second maid and then a third are also found dead--each missing one shoe--Cecily wants answers. The Pennyfoot has never witnessed such a peculiar crime, and Cecily has no idea where to begin. It's starting to look like the only thing she can do is wait for the other shoe to drop...
