Stone Cold Heart    by Caz Frear Order:  USA  Can Harper, 2019 (2019) Hardcover, CD, e-Book      Reviewed by Hilary Williamson Stone Cold Heart is the second (following Sweet Little Lies) in Caz Frear's London Metropolitan Police series starring twenty-something DC Cat Kinsella. Cat is partnered with Luigi Parnell, and both try to keep on the right side of DI Kate Steele. As this episode opens, young Australian Naomi Lockhart is found dead, after attending a party thrown by her boss. Evidence soon points to sleazy Joseph Madden, an obnoxious character who managed a coffee shop near police headquarters and had come on to Cat. As their Murder Investigation Team digs through the evidence, Cat remains haunted by the secret she keeps both from her colleagues and her lover Aiden - of evidence she suppressed relating to Cat's estranged father's involvement in the death of Aiden's sister Maryanne. If the truth comes out it would destroy both Cat's career and the relationship that's becoming more and more important to her - but living the lie is damaging too. Cat's stress builds when Uncle Frank, a criminal close to her family, threatens her with his knowledge of what happened. Cat solves more than one case before it's over (in a conclusion I didn't see coming) but the sword of Damocles hanging over her life remains, exacerbated by a final communication she has with her Dad - will he fix things or make it all worse?
