This is the first Agathie Christie book I've read and it was a good place to start! 
 The story is of 10 people asked to an island getaway only to find they've been lured there under false pretenses. Murder quickly follows with each of them scrambling to find out who it could be and how can they save themselves. 
 The book reminded me of one of my favorite movies, Clue, but with a less hilarious series of events. 
 My next Agatha Christie pick, Murder on the Orient Express!
