DEFINITELY WORTH A READ (tho I'm a bit upset about the murderer's incentive)

It was thoroughly an enjoyable read!

I loved how it’s inspired by And Then There Were None but also made itself distinguishable from it.

Things I loved:

The story structure around mainland and Island, and how it wraps into one.
How the author plays with nicknames and actual names of the people.
It refers to a previous murder, but although we uncovered it, it actually have nothing to do with it.
Everything - all mystery is explained throughly.
Kept me guessing til the last moment.
What Ellery said about the modern Holmes is particular thought provoking (ironical as well)

Things I don’t like:
The murderer’s motive.
