Murder always barks twice - Jennifer Hawkins

A charming tea room owner and her excitable talking corgi will need to work together to bring a killer to heel in this delightful cozy mystery.

For ex-accountant Emma Reed and her beloved corgi, Oliver, opening Reed's Classic Tea & Cakes in the idyllic village of Trevena in Cornwall has been the fulfillment of a lifelong dream. Her cakes are popular, she has a host of wonderful new friends, and even a potential new romance. There's even time left over for plenty of long country walks with Oliver, who is not only the cutest corgi on record (at least to Emma), he happens to talk (at least to Emma). What could be better?

How about being asked to help cater the local Daphne DuMaurier literary festival?

But when the festival organizer is found dead and foul play is suspected, Emma, Oliver and their friends are plunged deep into a poisonous mix of village jealousy, family tension, money troubles, and secret love affairs. Emma quickly realizes it's up to her and her intrepid corgi to discover a canny killer whose bite is worse than their bark.
