Mary Lou poses as a guest of Mrs. Hilliard, the manager. She gets to know most of the guests and suspects several of them (an old maid who felt she should have inherited the house, the daughter of another guest, who elopes with her young man) before she moves on to the real suspect: a girl calling herself Pauline Brooks. ML realizes her mistake when she sees Pauline with another girl, Miss Jackson, and another guest id's Miss Jackson as the servant who cut out after two of the earlier thefts. ML realizes that there's a "secret band" of thieves working together to rob hotels.
Her search for Margaret Detweiler turns up that the girl was fired for theft from the store where she was working. Margaret was then offered a job by a mysterious Mrs. Ferguson, who witnessed the discovery of the theft. Of course, it turns out that Fergie is the head of the secret band (she planted the stolen item on Margaret), and Margaret is too good a girl to steal--she only stays with the loot, "under duress."
In the end, ML calls her dad to come help, and he's able to get everyone arrested, while ML drives out to the abandoned house to find the loot. She gets locked/boarded into the house by the local guy keeping watch. Mrs. Hilliard realizes something is wrong when ML doesn't come home that night and alerts Detective Gay. They come to the rescue and release her, arresting the watch guy, and finding Margaret in the process. They take all the loot back to the rooming house and distribute it to the residents, making a Merry Christmas for all.
- Max is ridiculously upset about ML leaving over Christmas, because she's going to miss some important dance, and he's the class president. He then shows up in Philadelphia for a couple of days to surprise her (sweet, because she's homesick) and proposes a secret elopement (creepy). What does he think they're going to do, find a JotP, tie the knot, consummate the marriage in the back of his roundabout, then reveal everything on graduation? Yeah, actually just that. Well, the roundabout is implied. ML is appropriately horrified. How Beverly Gray of her.
- In case you didn't figure it out, the previous two books took place over the summer between junior and senior years, and this book takes place over winter break of their senior year. ML is still 16 until spring.
- The secret band? Wasn't the word "gang" in use by this point?
- You know immediately that Pauline is going to be a bad guy because she's wearing "too much lipstick." If she were okay, it would have just been "bright" or "a lot."
- Illegal activity for this book: when ML gets trapped in the house, it's because she BROKE IN a window, then the guy covers it up when he notices it. It's not an intentional entrapment.
- Nothing happens to Margaret, even though she's been consorting with thieves for almost an entire year. I know she's supposedly coerced, but you think she could have told SOMEONE, if she's really so innocent.
- Pauline and the other girls disguise themselves as drunk men to get in people's rooms. I was kind of surprised by the mention of drunkenness/portrayal of drunken behavior. I did check; Prohibition was repealed in 1933, so it wasn't actually illegal, though.
- ML has a squirrel coat. And goloshes. And fashionable long snow pants.
- The Philadelphia thing pretty much confirms the Pennsylvania location for the first book/Mary Lou's hometown, Riverside.
- Edie does this in the other two books, but it's at its most annoying here: the upfront foreshadowing. Seriously, the end of every chapter is some variation on this: "Little did she realize at that moment how thankful she was to be . . . " Constantly. SHOW me, don't TELL me, Edie. Take me by surprise for once.
- Unlike some other breeder sets or canceled series, it doesn't hint at any ghost titles in the end. It actually ends in such a way to finish the series pretty satisfactorily, really.
- I love quaint inscriptions and bookplates. It's odd that this was owned by a boy, but I love he put that he was junior varsity, first team.
So, this series wasn't too bad. Lots of good fashion, very 30s, a little romance, three very different mysteries and settings, great cover art. My biggest complaint with the series is that I feel the secondary characters are lacking. They're either good or bad, without any real personality traits. These books totally need a Chubs. They're also not very gripping. It's not like the early Beverly Gray or Judy Bolton books, where I'm completely absorbed and have to finish and then read the next one, etc. I will say they're ahead of the times as far as being mystery-focused and stand-alone.
What's next? Shirley Flight, maybe? I did get inspired by aviation memorabilia on Antiques Roadshow this week. Speaking of which, I just love it when people are overwhelmed and cry on that show. Especially old ladies.
