What a ride! Very enjoyable audiobook.

What to expect?
- Agatha Christie's And then there were none style locked mansion in isolated island with high tides mystery
- Dysfunctional family 
- Rich grandmother and will reading. As you can guess, the will is not pretty
- Murders at the strike of the clock
- clocks! and flowers!
- engaging writing style that reveals just enough to keep you turning pages

The not-so-good parts
- The predictability! It is such a shame when a murder mystery gets predictable. But I thoroughly enjoyed the story inspite of the predictability. I was simply hoping I would be proved wrong. Alas! 
PS: not just the mystery part. you can really predict the characters if you've read enough mysteries. As someone who isn't a mystery addict, it was pretty easy even for me. But I still stand by what I said. You keep hoping you are wrong because the writing style is engaging.
- ok that ending was a bit weird

Verdict : bingeable weekend read.
