The author makes a really interesting point about crime on board ships, especially cruise ships and at sea. There is a huge loophole where jurisdiction is concerned.
Can the crime be pinpointed to a certain body of water? Is it international water or a specific country?
In reality crimes on board are usually left to the security firm or guards on each individual ship, and they always have the best interest of the company at heart. There is also a dark statistic about actual crime swept under the carpet and kept on the down-low.
This has a Christie and Hitchcocky Rear Window mystery style feel to it.The plot and solution are pretty evident because of that, but then I read and watch a lot of Christie.
Lo witnesses something after a long night of drinking. When all evidence of said event is erased it makes her look paranoid and unstable. Nobody believes her and Lo finds herself isolated with no avenue of escape.
You get the sense of claustrophobia and the frustration at the lack of contact with the outside world. How each and every person becomes a potential suspect. No one can be trusted.
It is the type of cosy mystery I enjoy. It would be interesting to see Ware create the same type of crime or mystery scenario with a fixed character as a detective, for instance.
