Ordeal by innocence by Agatha Christie

I like it very much, even if it doesn't have anyone known inside. There's no Poirot and no Miss Marple, no known names are mentioned. Still, it's a great book, a big drama that concentrates on a subject that it was clearly dear to the writer, since I've read about it in many other books. There are cases in which, more than catching the murderer, the important part is to clear the innocent's position, to avoid their life being ruined by suspicions and rumours. This book is all about it. It's a very interesting story: two years ago a woman was killed and one of her adopted sons was arrested and imprisoned, and there he died of some illness, I don't remember exactly which one, and I've just read it :-/
The kid Jack kept saying he had an alibi but nobody came forward for him so he wasn't believed. Fact is, that day he really did have an alibi, but Doctor Calgary could not tell anyone because he had an accident and forgot about it, then left on an expedition so read nothing about the case. Only now he realises what had happened, and thinks it his duty to tell everyone that Jack was innocent. He personally informs the family, believing that they'll be relieved to know that the son didn't kill the mother. Little he knows, though, because it turns out nobody is glad to hear what he has to say, on the contrary they are all troubled by his words. He will soon understand why. Given the circumstances, it is unthinkable that a stranger could have done it, therefore someone in that house must be a murderer. Rachel Argyle was a rich woman but she had disposed of her money for all of them so money doesn't seem to be a motive. She was a good woman, but she wasn't much loved. She had adopted two sons: Jack, the black sheep, always in trouble, who has been a little criminal all his life; Micky, who hated her because when he was a little kid he wanted to stay with his poor drunken mother, instead she left him with Rachel in exchange for a hundred pounds; and three daughters: Mary, the first one, wanted to be adopted to have all the comforts Rachel could give her, and then married the man she loved even if Rachel didn't approve her choice, and wanted to live with him away from the rest of the family; Hester, abandoned by her real mother, who always resented Rachel's invasive presence and always remained an insecure child inside; Tina, the daughter of a prostitute and a southamerican sailor, the only one that truly loved Rachel and was grateful for the life she had given her. They all lived in the same house with Leo, Rachel's husband; Kirsten Lindstrom, a swedish nurse working for them; and Gwenda Vaughan, Leo's assistant, in love with him.
Jack was the perfect suspect for everybody, and now that he's declared innocent, the lives of the others are thrown into a circle of troubles and suspicions. Realising the consequences of what he did, Doctor Calgary is determined to find the right murderer in order to clear the positions of all the innocents. To do so, he'll start studying the characters of the victims: Agatha Christie was really the one that invented the BAU; as Hotchner (from "Criminal Minds", of course) always says: we study the victims to profile the unsub. :-) Doctor Calgary does the same thing, studying Rachel and Jack to uncover the real murderer. Unfortunately he'll be too late to avoid another victim, but I'm glad to say that Christie is the usual romantic one and saves a girl, only wounded, concluding the book with a bit of romance :-)
