I was deleting the audiobook for this at work, but it sounded interesting, so I grabbed the book (I hate audiobooks).
Overall, it IS interesting, in a vague historical way. Many times, for whatever reason, captains of whaling vessels on multiple-year voyages were ofttimes amiable on shore, but raging sadistic lunatics at sea. Although no reason is given, obviously being away from shore for months on end, gutting whales if you could catch them, eating the same nasty food day after day, not being home for years, dealing with storms, pirates, and cannibalistic natives in the Pacific Islands of the 19th century, and the malnutrition of poor diet and scurvy, no doubt played a role. Conditions were crowded, smelly, foul, reeking of dead whale carcass, the normal squabbles of men of different countries and abilities and races, personal prejudices - many men abandoned ships in any port that seemed friendly.
Such was the fate of the Sharon, and more. Druett builds up little teasers all along - "They had no idea what they were in for," "Little did he know how far it would go," etc. In the end, the captain of the Sharon, Howes Norris, picks a man as his scapegoat, beating and torturing him for no reason, until one day he finally beats him to death. Norris beats many of his crew inhumanely, but for some reason picks on this one especially. Norris is also silent about the whole thing, never mentioning the issues at all in his log, against all maritime law. Many of the crew try to mutiny, many take off at the next port of call, and many of the replacements they acquire are native Pacific Islanders. Running short-crewed, while the boats launch to chase a whale, two of the PIs murder Captain Norris with whale spades. One man is witness who lives. Some of the crew record the events in their own diaries, which don't show the First Officer in good light, either.
The first officer takes the ship and runs it for two years before returning home, and also has issues with the crew. The news of Norris's death and the failures of the cowardly first officer are told to the newspaper by one crewman, ruining the reputation of the first officer.
Druett tries to tie Norris's cruelty and death as Melville's basis for Captain Ahab in Moby Dick, as Melville was cruising in and out of the waters at the same time on whale boats, and most likely crossed paths with Norris - but she can't provide any details. And that's the biggest failure of the book - 90% of it is speculation - detailed, probable speculation, but still speculation. The crew sometimes didn't write in their diaries for 6 months at a time. Norris and his officers never said a word to anyone about his treatment of the crew, top secret stuff. Most of her information is taken from a few records and newspaper articles, but there just isn't enough to make this story top of the line thrilling. All the buildup, and then no one actually sees the murders - they come upon the mangled corpse which was unrecognizable because the ship's pigs had gone to town on the skull. While the information was interesting, and if you're into whaling history you'll probably like this, but there isn't enough information to make this a top-notch murder mystery.
The one thing I did find quite interesting is the table she includes in the back, which is the information on the crew given when they sign on. These men were TINY by today's standards. TINY. The tallest were of 5'9", while far more of them are 5'3", 5'4", 5'2", and one tiny guy at 4'9" - full grown men, doing all that hauling and lifting and harpooning and rowing - sometimes hours on end. It's a wonder they were able to do any of it at all. It's a testament to a life of malnutrition, these stunted men. I wonder what they would have thought of someone like Schwartzenneger in his prime.
Unless you're into whaling stories, you can skip this.
