Danger in a Red Dress is an enjoyable book with a rather odd title - I don't remember any red dresses appearing in the book (although there was a black dress towards the end). It features nurse Hannah Grey, who finds that being left a legacy by one of her former patients is a double-edged sword when it sets his family against her.
While under investigation for professional misconduct led by the family of the deceased man, Hannah is offered another job, as nurse to an old, cantankerous, housebound woman. Hannah takes the job - and gets a lot more than she bargained for. She finds herself in the middle of a conflict between Melinda Manly and her son, Carrick, over whether Melinda knows the whereabouts of a great deal of money that her husband embezzled. Carrick needs the money himself and hires Gabriel Prescott to bug the house and find out whether Melinda knows the location of the money.
Gabriel, in a voyeuristic manner, finds himself intrigued by Melinda's nurse, Hannah Grey. He carries out a flirtation with her by telephone, but before he has a chance to meet her properly, Hannah is running for her life after apparently murdering Melinda. When Gabriel eventually catches up with Hannah, now living under an assumed, he has to decide if she is innocent of murder and, more importantly, if she will ever trust him.
Danger in a Red Dress is an enjoyable read with the underlying mystery of the location of the money, spread over a year and set in different places. I didn't find Hannah a very appealing character - her morality seems a little variable (although perhaps this is more true-to-life than many heroines of this kind of book); Gabriel is more likeable. One failing of the narrative is that some elements of the plot come across as unrealistic. The obsession with money and talking about money and penthouses and millions strikes me as distasteful, but that may be my British dislike of ostentation showing through. However, the story kept my interest and is apparently the final book in a series about the Manly brothers. As such, it works well to round off the tales of this group of brothers.
