An Uplifting Murder — Elaine Viets

Mystery shopper and mom Josie Marcus knows how to keep a low profile in style. On her newest assignment, her former teacher -- now working in a lingerie shop -- is in need of some serious support...

When Josie is assigned to mystery-shop a chain of lingerie stores, she's surprised to find her former high school gym teacher, Mrs. Hayes, working as a manager and self-appointed "C-cup counselor." But that's nothing compared to the shock of finding another high school acquaintance murdered in a restroom near the shop, her hands bound with the bra she just purchased.

Mrs. Hayes quickly becomes the prime suspect. A secret from her past that she's been reluctant to get off her chest could be a motive for murder -- and her alibi is flimsier than the camisoles she sells. But the victim had plenty of enemies, and it's up to Josie to bust out her sleuthing skills to expose the real killer.
