Nailing a murderer is difficult... but so is dealing with a cranky talking dog. When the owner of Hammer and Nail Hardware is found dead, Gina's most loyal customer, Erika, becomes the prime suspect. Despite having every reason to kill Molly Burton, Erika vehemently denies involvement and pleads with Gina to help uncover the real murderer. With almost all evidence pointing to Erika, Gina and her talking dog, Daisy, along with Deputy Trevor Hutchinson, delve into the secrets concealed behind the aisles of the hardware store. However, the clues they unearth leave them with more questions than answers. Adding to the chaos, Gina takes in a bonded pair of dogs who prefer solitude. Daisy is determined to break them up, despite Gina's pleas to let them be. As danger escalates, can Gina and Daisy hammer out the details and expose the true murderer?
