How do TV series’ fare when compared to the books they’re based on?

I discovered Liane Moriarty (what a splendid surname for a writer of murder – well, sort of – mysteries to have, by the way) rather late in the day. Somehow, her major breakthrough novel, The Husband’s Secret, passed me by when it released in 2013. It was only after I read her 2014 book, Big Little Lies, that I was intrigued enough to go back and see what else she had written. Suffice to say, I was not disappointed. And then, last year Moriarty released her latest novel, Truly Madly Guilty (yes, she is rather prolific that way) and I was well and truly hooked. And like most newly-converted people, I went around recommending her to all my friends and acquaintances (“Yes, yes, I know, you’ve never heard of her; but believe me, she’s fantastic!”).
