Flash Memory - A Lost Hat, Texas, Mystery, #2

Nature photographer Penelope Trigg has landed the job of her dreams: documenting the transformation of over-grazed rangeland into an eco-dude ranch and spa, owned by her boyfriend Tyler Hawkins. Then a body is found on the ranch and Ty is arrested. The victim was an aggressive real estate developer with his greedy eyes on Ty's land and Ty's sister Diana, who is almost engaged to the senior deputy sheriff.
Clues put her at the center of the puzzle. Determined to prove Ty's innocence, Penny stirs up Diana's old flames, trying to shed enough light to develop an alternative suspect. She mainly learns how to lose friends and annoy people, until she realizes someone has been manipulating the evidence. But is Ty the framer or the framee? Penny uses her eye for detail and her camera's memory to put the picture together and reveal the killer.
