This is the first in the Hannah Swensen series. Hannah Swensen owns The Cookie Jar, a cookie shop in Lake Eden, Minnesota. She goes out to get her delivery of dairy and discovers the driver dead in his truck. Her brother-in-law, Bill, is on the case and Hannah helps him investigate so he can be promoted to detective. Along the way, Hannah discovers another body. It wasn't the best "cozy" mystery I've ever read but it was cute and had lots of good cookie recipes.
