In the Chill of the Night is Gregg's seventh mystery set at Crooked Lake which is Keuka Lake, the Y-shaped Finger Lake located in central New York State. Gregg uses fictitious names for the local counties, villages, wineries and businesses in the immediate area of Keuka Lake, but Corning, Elmira, Rochester, etc. retain their real names and anchor the setting geographically. In early spring Cumberland County Sheriff Carol Kelleher is confronted with two murders within several days of each other. Her professor husband and partner in solving crimes, Kevin Whitman, is teaching classes at his college located in New York City. Not only is there the question of whether these two murders are linked, but the local militia is playing "games." Near-tragic events bring Whitman back to Crooked Lake to help connect the dots. Gregg, a retired academic and a long-time summer resident of Keuka Lake, captures the culture of year-round and summer residents, as well as the ambiance of Keuka Lake. I have spent summers at Keuka Lake for more than 50 years and can attest to his accuracy. While the motives are contemporary, I found the ending weaker than his previous mysteries. Even so, I look forward to next year's Crooked Lake mystery.
