After John R. Neill died, the Oz series took a rest for a couple years, but it returned in 1946 with The Magical Mimics in Oz, by the series's fourth author, Jack Snow, and third artist, Frank Kramer.

Jack Snow was the first person to be a bona fide Oz fan to write an Oz book, and you can tell; it's the kind of book where characters do things like say, "Oh, wasn't the Forest of Burzee where Santa Claus was raised?" so that you know the writer has read The Life and Adventures of Santa Claus. (Although, weirdly, he gets the Guardian of the Gates confused with the Soldier with the Green Whiskers. Rookie mistake!) He was also specifically an L. Frank Baum fan; while Neill built on what Thompson had established, Magical Mimics doesn't reference any characters or concepts from after Baum; you could go straight from Glinda of Oz to Magical Mimics without missing a beat. And actually, it would read pretty well; Baum always included some minor characters from the last couple books in his most recent book's celebration scenes, and Lady Aurex from Glinda shows up in this book's. But if you are reading in publication order, Glinda was twenty-six years ago, so the odds are very much against you remembering her! A lot of minor characters that Thompson and Neill hadn't cared for pop up here in minor roles, like Button-Bright and Cap'n Bill. (I did add in a reference to the events of Runaway when reading aloud though; it fit quite naturally into one of Scraps's scenes.)

The premise of Magical Mimics is on the darker end. As always, someone is trying to take over Oz, but it's one of the more successful attempts, like Thompson's Wishing Horse. The Mimics are shapeshifters who want to invade Oz, but can't because of a spell of protection cast by Queen Lurline when she enchanted Oz. What they figure out, though, is that they can replace people who came to Oz after the spell was cast, so when Ozma and Glinda leave Oz on state business, they sneak into the Emerald City and replace Dorothy and the Wizard. Dorothy and the Wizard wake up in prison in Mount Illuso, the Mimics' home, while the residents of the Emerald City go increasingly concerned about Dorothy and the Wizard's strange behavior.

To be honest, I kind of wanted something more creepy and more complex, with Mimics slowly replacing Oz character after Oz character, while some other characters desperately tried to figure out what was going on. As it is, the book is pretty simple: the Mimics replace Dorothy and the Wizard, the other Oz characters wonder why they're acting weird but don't really make any progress or discoveries, meanwhile the real Dorothy and the Wizard meet a fairy who explains everything to them, she takes them back to Oz, and she defeats the Mimics. But perhaps Jack Snow knows his audience better than I do, because my five-year-old kid was totally on edge and nervous even with this very limited threat posed by the Mimics. They did not like that the Mimics replaced Dorothy and the Wizard, and did not like the tense chapter where the Mimic horde invaded the Emerald City and replaced everyone. So I guess it had enough jeopardy for the target audience!

Overall, I thought it was fine. I wish there had been more clever problem-solving by the Oz characters. Much like a Thompson novel, ironically, this one mostly sees the main characters stand around while a previously unknown powerful magic user takes care of everything for them. Dorothy and the Wizard don't do anything interesting to get away from the Mimics; the Emerald City characters don't do anything clever to figure out what the Mimics are up to. Toto turns out to be the real MVP of the novel, instantly realizing Dorothy has been replaced, evading capture by the Mimics, and striking at the Mimic King and Queen when everyone else is paralyzed by indecision. (The Scarecrow also shows some minor cleverness, admittedly, delaying the Mimics until Ozma and Glinda return to deal with them.) Thompson never did much with Toto, so it's nice to see him do some interesting stuff. Snow has the kind of languid pacing Baum often did, as opposed to the frenetic pacing of Thompson and Neill; Oz may be in danger, but Dorothy and the Wizard can still spend two chapters looking at a garden! Snow also captures a lot of Baum's sense of whimsy; both Pineville and the Story Blossom Garden feel like the kinds of places he might have thought of, not Thompson.

I'm sorry to say, though, that not only is Frank Kramer in third place for Famous Forty artists (thus far), it is a very distant third. There is an occasional nice picture (the one of Toto as Sherlock Holmes is fun), but overall most of his illustrations seem to aspire to competent at best. Baum hit gold with both W. W. Denslow and John R. Neill, so it's sad to see the publisher scrimping this time around.
