"Mysterious investigation stories on ships" might be one of my new favourite genres now - this was so, so good! As with Turtons first book, I couldn't put it down, missing my stop on the train on more than one occasion. However, similar to my reading experience with his debut novel, the ending was the only part where I stumbled. I hated it, then liked it, then despised it, then was ok with it - and as of right now, I'm unsure. Either way, I can't wait for his next book!
