‘Two can keep a secret’ is a young adult thriller.As mystery and thriller lover it is such a good story.This is a murder mystery story. The main two characters and the narrators of the story are Ellery and Malcom. This story is full of secrets and mystery which we are dying to get out of. The story goes on by the thoughts and conversations of this two characters. This story is a combination of mystery, a little romance and emotions. Ellery is murder mystery addict.
