CRYING OUT LOUD is #8 in the Sal Kilkenny series. I read it without having read any of the previous books in the series but never felt lost.
There were three main threads in this book:
1) There appears to be an "on-off" romantic relationship running through the series between PI Sal Kilkenny and her "housemate" Ray. Currently it's on. Generally, I find these sequential on-off romantic relationships boring (with the exception of McDermid's Tony Hill/Carol Jordan series), but it plays a very small part in this novel and so didn't annoy me.
2) A baby was left on Sal's doorstep with nothing but a note asking her to "Please take care of the baby." No signature. No explanation. This is the "crying baby" of the title, and too much time is spent worrying about this baby, who continuously upsets everyone in the household. Frankly, I agreed with Ray that Sal should report it to the child protection agency. Even though there is an explanation, in the end, for why the baby was left with Sal, it seemed incidental to the main plot of the story.
3) The only fascinating part of the novel was the case Sal is hired to solve—the murder of a man who had both a wife and a mistress, and was planning to leave this wife. Both the wife and the mistress would have been prime suspects in this murder case, but both had impeccable alibis. A homeless drug addict was convicted of the crime, but his half-sister does not believe he is guilty, and so Sal is hired to find evidence of his innocence. This is an intriguing case and I don't feel that enough space was allotted in the book to all its interesting twists.
I still enjoy Cath Staincliffe's writing style, although in this novel, PI Sal Kilkenny annoyed me. I wish she had spent more effort exploring the murder case and less effort worrying about the crying baby. I think I will try one more Sal Kilkenny novel in case this was just a misstep on the author's part. Three stars, mainly because the murder case was so interesting.
