Terrific combination of romance and suspense. Anna is the youngest of the six Hudson siblings and a private investigator like the others. She occasionally helps with the family's cold case investigations but primarily works for another firm. As the book opens, she is injured during one of her investigations caught in a deliberately set fire.

The arson investigator assigned to the case is Hawk Steele, the man she had a one-night stand with a few months earlier. She has been putting off telling him that she is pregnant, but the cat is now out of the bag. Hawk, a loner by choice, is stunned but determined to be a father to his child.

Neither has forgotten the night they spent together. Hawk wants marriage, but Anna will only marry for love. With Anna in danger, Hawk's protective instincts are aroused, and he is determined to keep her safe. As they investigate the fire and subsequent attacks on Anna, the feelings between them strengthen.

I enjoyed watching loner Hawk deal with the Hudson family, their closeness, and their involvement in each other's lives. The scene with Mary and the puppy was hilarious.

The suspense of the story was fantastic. I was glued to the pages as the attacks on Anna intensified, and the entire family and Hawk searched past cases to see who might be behind the attacks. The twists and turns were incredible. The final confrontation was a nail-biter and had me on the edge of my seat until it was over. I especially enjoyed Anna's part.

I look forward to reading the rest of the series. I'd like to know if they find out what happened to their parents. ( )

Cold Case Investigation by Nicole Helm is an entertaining romantic suspense. Cold Case Investigation is the third book in the Hudson Sibling Solutions series. It can be read as a standalone, but reading the series in order allows you to get to know the Hudson siblings and the other characters. Cold Case Investigation is my favorite book in the series. I enjoyed getting to know Anna Hudson better. Hawk Steele is a loner, but that will not work if he is going to be involved with Anna. I like how the Hudson siblings watch out for each other (a protective group of siblings). There is a scene with Mary, Hawke, and a puppy that had me laughing. Mary was not taking no for an answer. The characters are developed, and they have emotional depth. The mystery was full of action and suspense. I loved all the twists, turns, and drama. Cold Case Investigation had me staying up late to find out the resolution. ( )
