DEEP END by: Sam Hutton

Everything starts with two spies that simply wanted to explain what they did during their job to Maddie, the daughter of the boss of those two spies and protagonist . Whilst trying to explain everything, they tripped into a couple: Grace, the daughter of a big business man, and his boyfriend Dean; they were carrying twelve dimonds worth about two million dollars. Maddie got interested and decided to interrogate them. Grace and Dean were both really scared and so blurted out everything to Maddie which then discovered they had to meat with Bryan a very big business man. So Maddie convinced her two friends to get the places of Grace and Dean to discover something more. “Grace” and “Dean” were imprisoned from Bryan because he wanted to threat the father of Grace saying that if he wouldn't want to make some business with him he won't see his daughter again. In the end the police saved Maddie and Alex, which was one of the other two teenager spies (impersonating Dean), whilst Bryan has been put into prison.
