All evidence points towards suicide, but Jack is convinced there’s more to this case than meets the eye and turns his attentions to her family to be. With the victim's room locked from the inside and all suspects in different locations around the hotel, how could any of them have committed murder? Puzzled by a single painted nail on the victim’s hand, Jack is determined to prove foul play, despite the Commissioner insisting on closing the case. With a distinct lack of physical evidence, the team have a tough task on their hands.
