Two murders, too many suspects!

When Tracy Andrews, night clerk at the Eden Quick-Mart, is murdered along with an elderly customer, there's no shortage of suspects. Tracy liked men more than a married woman should, and her estranged husband, a Raven University police officer, knew it. Did he lose it and kill Tracy and her customer, did Tracy put too many demands on a boyfriend, or did a spouse of a married lover decide she'd had enough? Or was it a simple robbery gone wrong?
 
No one looks at the elderly man killed with her, but when someone breaks into his home, Eden police detective Jo Valentine takes a closer look. What she doesn't find surprises her.
