What I like the most about the story, and what the readers should notice if they want to understand what is alluring in this story - is that a main part of the story stays "hidden" from us - why was the man assassinated? Who is that assassin? Why did the boss want him dead? Why is the dead count significant?
That's what makes the story so enjoyable - you are not constricted to a definite detailed story - you are provided with a good frame and you should let your imagination fill the gaps with whatever pops up.
I am now reminded of a series of books I read when I was young - in certain pages you had the option to skip to a few options of the continuation of the story and sort of great your own entwined and tangled plot. It was fascinating as a child but today I prefer stories like this one you just read as it lets you have countless plots.

Thanks for an interesting and imagination provoking story!
