I'm going to get this out of the way right off the bat: this is one of those "cozy mysteries" where the amateur detective dates a cop. The romance is garbage, because it's always garbage, and we'll get into specifics later on, but everyone considering reading this should be forewarned about what they're getting into.
Anyway, Lauren Elliott follows the cozy mystery setup to a T, because if there's one thing I've learned from my foray into this subgenre, it's that its fans demand nothing less than rigorous adherence to tradition (see - authors insisting to pretend that local cops in small-town America are exactly like the polite local constable who popped 'round to the vicarage to have tea with Miss Marple once a week). Our heroine and future amateur detective is Addison "Addie" Greyborne, who - sing along if you know the words - returns to the small town of her youth following a traumatic event, and opens a twee small business. In this case, the traumatic event is the murder of her fiance, and the twee small business is a bookshop. Addie is back in Greyborne Harbor because her distance great-aunt has recently died, leaving Addie her house and a small fortune. When Addie moves in, she finds her aunt's house crammed with an extensive collection of rare books, and since Addie formerly worked as a rare books appraiser, she decides to open her own shop and sell the items from her aunt's collection. Oh, and also some guy gets murdered and Addie decides to investigate
Here's how much Lauren Elliott does not care about her own murder plot: the victim isn't even an established character. The first time we learn this man's name is when the news of his death breaks, so obviously we as the reader don't really give a shit either way - we're only supposed to care if Addie solves the crime because her best friend has been wrongly accused of the murder. Elliott is clearly way more interested in the romance between Addie and the cop investigating the death, so one wonders why she didn't just write a straightforward romance, and then I would have at least known to avoid it, because a plot description would have clued me into what I was looking at.
Listen, I'm trying not to harp on individual authors who make this choice. But Murder by the Book was published in 2018 (for context, the Tamir Rice murder was in 2014), and I think that if you're an author writing a murder mystery set in modern day America, you have a certain degree of responsibility when it comes to portraying the way many people in this country view the cops. Sure, your detective needs an inside source within the local police force so they can learn details about the case, but there are so many other ways to do it besides a romance. It's lazy and bordering on irresponsible.
Or at the very least, can we not make the cop love interest such a fucking dick? The guy in this one is the worst, and if you think I'm being biased (which I am, duh), then please enjoy this excerpt where Cop Love Interest comes to Addie with important news:
"He sauntered past her over to the coffee machine. 'Want one?'
'No, I don't want coffee. I want to know what's got you grinning like the Cheshire cat.'
'Everything in good time.' He dropped a pod into the machine.
She stood back and crossed her arms, tapped her foot, and glared at the back of his head. He was silent as his coffee brewed. She opened her mouth to speak, but shut it when he slowly tore open a sugar packet and poured it into the steaming paper cup. Believing he was done, she opened her mouth again. Without turning around, he raised his finger to silence her and picked up a spoon, methodically stirring his coffee. By this time, her cheeks were burning and beads of sweat were forming inside her collar. When he was finished, he placed the spoon on the counter, took a long sip, stretched out his rigid shoulders, and sighed. Her jaw tensed. She took a step toward him. He spun around, a sly grin across his face, and then he burst out laughing.
'Darn you.' She stamped her foot. 'Stop with the teasing.'
'Ah, but it's so much fun.'
'What has you in such a great mood?'
'Well, partner' - he winked - 'it seems we found enough evidence today to place a reasonable doubt on Serena's charge of second-degree murder.'"
I hate this. I hate it so much.
For context, the "Serena" they're talking about is the one who's been falsely accused of murder. She also happens to be Addie's best friend and the cop's sister. So Elliot has written a scene, which she genuinely believes is cute, where the cop has found evidence absolving his own sister of murder and is about to tell her best friend, but then this fucking guy decides that what he really needs to do first is a hacky, "don't talk to me until I've had my coffee" comedy routine. WHY. HOW COULD ANYONE POSSIBLY FIND THIS CHARMING. The man learned his sense of humor from a thrift store coffee mug and I'm supposed to root for him to make out with the protagonist?!
God, and the actual mystery isn't even that good.
