No strangers here
(Book)

On a rocky beach in the southwest of Ireland, the body of racehorse owner Jimmy O'Reilly is propped on a boulder, staring sightlessly out to sea. A cryptic message is spelled out in stones next to his body, and a vial of deadly veterinarian medication lies nearby. Detective Inspector Cormac O'Brien is determined to unearth every last secret. Meanwhile Dimpna Wilde returns home to Dingle after years away: her mother is rumored to have been in a relationship with Jimmy; her father's dementia is escalating; and her brother is avoiding her calls. As Dimpna takes over the family horse business, she's in a race with O'Brien to uncover the truth-- no matter how close to home it strikes. -- adapted from jacket
