The Alibi by Sandra Brown
Luke is dead at the hotel, shot 2 times. They inform his wife and she's not surprised he's not been murdered from his lovers husband. He has had many affairs in the past and although they are married, live in the same house, she knows nothing of his style or meetings of his life.
At the hotel there was also several others who had come down with food poisoning that may have seen the murderer. The cops try to get through to the ER doctor that they must talk to the people right then and there to help solve the murder case.
One investigator had spent the night with a woman he had met at the fair. She left before the next day and now he knows why she was on the phone when he walked into the bedroom and who she is and who she is related to.
Was never just a simple death, a lot of others are involved: unknown relatives, blackmail, insider trade secrets
Love that they staged the scene to catch the real murderer at the end.
I received this book from Net Galley in exchange for my honest review.
