The London Eye Mystery by Siobhan Dowd
My rating: 4 of 5 stars
I think I'm getting better at solving the mystery. It wasn't exactly Agatha Christie, but it was written in such a way that you COULD solve it, if you paid close attention. (Not like Chasing Vermeer, which I really didn't like for that reason.) And I did figure it out, so I'm proud of myself. And it was still interesting enough that I kept reading to find out if I was right!
Ted and Kat's cousin Salim is visiting London. Ted and Kat watch him get on the London Eye, and follow his pod around, but when it returns to the bottom, Salim isn't there. Next, they have to find out what happened and where he is.
Ted thinks differently (I think it's Autism or Asberger's, but they never name it) from other people, and this helps him figure out what happened. In this way, it's almost like a kids' version of The Curious Incident of the Dog in the Night-time. Good stuff.
