Solution Diagram
This is the solution given in the book, however I think it is wrong.
In my opinion, white can kill after (see next 2 diagrams)

white kills black? I disagree, white in the middle was captured when black played 2

white kills black (continuation)?
a and b are miai, black dies.

Correct solution Diagram (?)
Therefore, I think this should be the correct solution diagram.
Anyone agrees, or am I missing something?
Djaian First of all, your solution doesn't work

white does not kill black here.
What you didn't see is that black can kill the 2 white stones in the corner if white tries to kill black.

white kills black.
I thought white could save his corner stones by connecting underneath...

continuation.
...but that's not true. See the following response of unkx80. Thanks.
