Sweet, Sweet Poison — Kate Wilhelm

The detectives. Charlie Meiklejohn and Constance Leidl were an unlikely pair of detectives. He was a former arson investigator, she was a psychologist. They had a knack for unraveling a mystery, and mystery always seemed to find its way to their door. The clients. After winning the lottery, Al and Sylvie Zukal moved from the Bronx to escape the noise and crime. They thought quiet, picturesque Spender's Ferry would be the perfect sanctuary, even if none of their wealthy neighbors would have anything to do with them. But when their guard dog and a local man were poisoned, the Zukals feared that their newfound haven might become their final resting place. The mystery. Asked to investigate the deaths, Charlie and Constance discovered that the serene surface of the rural retreat hid dark secrets, and that someone was willing to kill, and kill again, to keep them from being revealed. If they weren't careful. Charlie and Constance wouldn't be the antidote to the crime, but the next victims.
