As the new owner of the Coral Shores Veterinary Hospital, Dr. Emily Benton is in over her head. When she makes a house call at the home of her client, Mrs. Eliza Klein, she finds the woman's terrier, Elvis, in a state of distress and Mrs. Klein face down on the floor-dead. Emily immediately contacts her brother, Deputy Sheriff Duncan Benton, for help. The cause of death is later determined to be nicotine poisoning, triggering an official murder investigation. Who would want to kill a retired piano teacher best known for her animal charity work? Emily is caught up in the middle of the drama when she brings Elvis into her home. The little terrier's strong canine instincts drag Emily further into the investigation, putting them both at risk. While Emily and her best friend, Anthony, take on the role of amateur sleuths, Emily's brother and his very handsome colleague, Detective Mike Lane, work to uncover the truth and get justice for both Mrs. Klein and Elvis.
