Last Seen Alive by Carolyn Arnold

The woman lies so still as her blood soaks into the soft bedcovers beneath her. A tear runs down her face as she looks at the wedding band on her finger. She had loved her husband so much…
When Detective Amanda Steele unexpectedly reconnects with an old boyfriend, the last thing she expects to see lying on his bed is the dead body of his wife, Claire, who walked out on him four years ago.
Logan begs Amanda to believe he’s innocent. But she doesn’t miss the gun on a nearby table, and she’s torn when forensics reveal that not only was this the murder weapon, but Logan’s fingerprints are all over it… Could he have been framed? Or is he using his connection to Amanda to get away with murder?
Determined to uncover the truth, Amanda retraces Claire’s last steps and finds that she visited her best friend the day before her death. But Amanda is devastated to discover that the friend died in a car accident just hours after meeting with Claire. What deadly secret connected them, and could more women be in danger?
But the killer is closer than Amanda realises, and when her beloved daughter, Zoe, is threatened, she’s suddenly in a race to find the final clue before the person she loves most pays the price…
