Submarines are horrible. They are cramped, isolated, and for a long time were very very dangerous. Parker has managed to transform these individual stories into a really fascinating collection. Occasionally, he assumes a greater knowledge of submarine construction than I actually add, but this is a minor niggle. Additionally, as British submarines have only been used in anger once since WWII, there are not many stories post-WWII. Although this is a bit unfair, because short of fermenting a horrible war, there really isn't much Parker can do about that. Grimly fascinating.
