A fast paced mystery with many interesting characters.
Here instead of one dedicated detective we find many ppl working on the case on their own accord, for some personal reasons. They team up and do some brilliant sleuthing and while Police is working side by side in his own way.. 
Finding clues and getting to know each suspect was interesting..
Story flowed very well ..
.
I won't tell what the story was coz aging I am stressing that you should read a thriller or mystery without reading a blurb 
.
About the ending..it was predictable ..
After reading lot of Christie's books we can guess the murdered here infact, we can also guess the reason behind the murder 
What we can't guess as usual is 
How he did it ...
