I am searching for a reference that contains a detailed discussion of most of the topics in Hilbert space theory. I am both interested in the geometry of Hilbert spaces and operators on Hilbert spaces.
I am familiar with several excellent texts on Banach space theory; for example, Megginson's An Introduction to Banach Space Theory and Albiac & Fanton's Topics in Banach Space Theory. However, I am not aware of similar types of books for the theory of Hilbert spaces.
The book that comes most closely to what I have in mind is probably Halmos' A Hilbert Space Problem Book. However, as the title of this book indicates, this book is meant as a problem book and not really a reference text.
I am familiar with general topology, abstract measure theory, and functional analysis; so it is no problem if the book has these topics as a prerequisite (as Halmos' book has).
All suggestions and comments are welcome.

(Caveat: while these all look promising to me, I haven't read any of them myself.)
