The Cane Mutiny (Den of Antiquity Series #13) in Bloomington, MN

Raising Cane
Abigail Timberlake Washburn understands the antiques game is a gamble — so she doesn't know what to expect when she wins the bidding for the contents of an old locker that has been sealed up for years. It's a delightful surprise when she discovers inside a collection of exquisite old walking sticks — and a not-so-delightful one when she pulls out a decrepit gym bag containing . . .
a human skull!
The last thing the diminutive South Carolina antiques dealer needs is to be suspected of foul play. So she grabs her chatty assistant (and future sister-in-law), C.J., and heads out to search for a killer they can stick it to. But this cane case will be no walk in the park — with its arcane clues hinting at poaching, counterfeiting, smuggling . . . and homicide, of course. And when a fresh corpse turns up, things are about to get
really
sticky for Abby and her staff of one.
