Not a book, but a 1950's TV show. Some hard hat divers involved. Since it's been so quiet around here lately, I figured you guys might enjoy something like this......

There is a whole TV series on youtube which I have been enjoying this cold winter. Not vintage diving persay, but who could turn down a show about our Fleet submarines sinking the Japanese in WWII.
