Not that I have any great desire to reread the series, but I have curiousity, and dammit, it shall be slaked!
When I was a kid (early 70s), I read a series of books about the fun and adventures of a submarine during wartime. One book was called The Tattooed Man, I think. It was about a new boat captain named Jarvis. 90% of the books were little more than “The bulkheads began to creak and buckle as depthcharges exploded all around.” The other 10% was about the cook offering to make egg sandwiches for the sailors.
This ring a bell with anyone?
