Death of a Honeymoon

Detective Mark Taber and his new bride Donna, an amateur sleuth, are ready to take a much-needed break from crime-solving and finally enjoy their long-awaited honeymoon in the quartz-rich mountains of Arkansas, but unfortunately for them, crime never takes a break. When their car breaks down at the site of the first murder the county has seen in a century, they find themselves in a bind - no transportation and at the center of an overwhelming firestorm for an overworked sheriff.
He needs their help. Will they temporarily forgo their plans to find a murderer or will the possibility of netting quartz clusters and county fair winning recipes pull them in another direction?
