The back cover blurb, reprinted at the top of this Goodreads page, provides quite a few details of the story, including several items I would otherwise have to put inside spoiler tags. Maybe we could call it a spoiler blurb? For example, someone does get killed, but you may exhaust your patience waiting for it to happen if you think this is going to be a typical murder mystery. If the blurb hadn't said "murder" and "killer," I couldn't have, out here in the open. Nor could I have told you that two of Lexi's cases might be connected if the blurb hadn't, well, blurbed it to you.
On the other hand, the blurb is distinctly misleading about Lexi's cases as a newly minted private investigator. There are only (!) three of them. She "goes undercover as a plush pony" (yes, she does) to spy on suspects in her investigation of sabotage at a major hotel; that's the first case her boss Solomon has assigned to her, and he has her working solo and reporting privately to him only. She's really undercover as the hotel manager's new assistant, and the manager is the one who turned to Solomon's agency.
That pony disguise (with her best friend and many readers' favorite, Lily, bringing up the rear) is the high point of the humor that made this story so enjoyable. The blurb just says it's at a "Bronie" conference. Did you know what a Bronie is? I didn't. It's carefully explained as an amalgam of "bro" and "pony" and it refers to grown men who love little girls' plush pony toys and love to talk about them with other grown men. And they have conventions where they carry on as though it's ComicCon. It is indeed comic (and not made up by the author).
So the hotel that's hosting the three-day Bronie convention is being sabotaged in many little ways for some reason, perhaps to get the manager fired by the hotel chain, so he's a desperate mess and Lexi is under great pressure to catch the saboteur immediately if not sooner. That sets up even more funny episodes, thanks to her very clear, intelligent first-person narration and Solomon's instruction not to let the police in on this case until he calls them in. That means Lexi's policeman lover Maddox and her whole family (she's related to nineteen members of the city's police department, including her three brothers). She has to make them think the hotel assignment is a real return to temp work.
But she brought a proposed case to Solomon and he rejected it as not worth pursuing. A prospective client's friend has gone missing, and Lexi is so moved by the person's concern that she takes the case independently and pro bono, not letting the client know Solomon rejected it and not letting Solomon know she's working the case.
And then, more action that's not just pro bono but pro familia: her older sister Serena, the one who bossed her around so much in the first book, realizes that her husband Ted is cheating on her and needs Lexi to gather lots of evidence to take to her lawyer. Lexi's relationship with her sister improves and she's furious with Ted, who never fit in with Lexi's large extended family.
Those two pro bono cases are quite serious--one has pathos, the other fury--but those adventures in the big hotel had me laughing again and again. All in all, an enjoyable story that was hard to put down, but just like the first book in the series it had some editing flaws, really more at the level of proofreading this time. So I slipped into editor mode, made the corrections in my mind, and had fun reading the book.
What the proofreader should have caught: (1) Oddly between page 41 and page 91 (out of 303) I count eight British expressions that I don't think an American would use; the rest of the text fits the American setting. (2) Too many commas, quite a few inserted where they don't belong at all. (3) Missing words--every now and then it looks like a word got deleted by mistake.
This was more of an adventure, though the author clearly tried to write it as a mystery. In addition to a big red herring, it has a big blue herring (by which I mean that one part of the solution comes out of the blue). Result: partly a surprise at the end, partly no surprise. As adventure, though, it was fun to read. Three and a half stars rounded up.
