Case of the Bleus by Korina Moss
Case of the Bleus might have been my favorite in the series so far. This time around some of Willa's former co-workers are in town for the Northwest Cheese Invitational. They will also be attending the reading of Max Dumas' will along with his formerly estranged daughter. The daughter is supposed to inherit Max' cheese shop. The big question is who will inherit the secret to Church Bleu Cheese - how it's made and where it's aged. Instead, all they get is a clue they have to figure out. Then one of the cheesemongers is killed, and Willa and her friends decide they need to "help" find the killer. So we have two mysteries - who is the killer, and what is the secret to the cheese.
The plot itself had several twists. The visitors to town each have their own angle and were definitely potential suspects. How the woman died was clear right away, but the who was more difficult...
