You may recognize Hall from his more popular book Mutiny on the Bounty.
This was a pretty good book. Set during the Napoleonic Wars, the ten chapters each explain how Dr Dogbody lost his leg. Some were better than others, but all were very entertaining. Dr Dogbody would make a great NPC! And I really want to go to a place like the Cheerful Tortoise, where Dogbody tells his tales. The stories are distinct, yet, the narrative is continuous: each night Dogbody's friends implore him to tell his story, and he pretends he won't. But eventually he yields.
Recommended if you like sea stories.
