I’m gonna read some books to the boy that aren’t these, for the next little while.
That said, yes, I still like the Three Investigators, while recognizing that the first one was quite a bit better than the next couple have been. The good news is, that doesn’t mean The Mystery of the Whispering Mummy was bad.
You can really tell it’s a different time: the mystery hinges around a mummy found 25 years earlier, which the professor who found him is considered the owner of(!), and he’s been graciously loaning the mummy to a local museum in Cairo. But when he decided to bring the mummy home to southern California for further study, that’s just a thing he can do, since he found it in a tomb back in the day. Like, there are modern rewritten editions of these books and how I wonder did they rewrite the central premise of the story to explain away that this is not the way archaeology works anymore?
Nevertheless, that premise settled, the story itself is pretty good, what with a plausible curse, a mummy who seems to be talking (but only to one man), villains who are sufficiently threatening, scary car chases, and also Anubis, because how are you supposed to mention ancient Egypt and just leave out Anubis?
