2)She told me she had baked a cake for her husband in prison.
3)I will inform my boss at the supermarket immediately, if I see anybody stealing things from the shelves.
4)He threatened he could shoot the hostage, if they didn't give him all the money he wanted.
5)She said that despite all the dangers she enjoyed her job as a policewoman.
6)The bank roobber warned me, don't press the alarmbell.
7)He inquired whether I saw the Old Bailey when I was in London.
8)If the politician had not been assassinated, do you think things could have remained the way they were?
9)The policeman asked me If I had any previous convictions.
10)Even if you decide to keep all the stolen money, could you able to sleep at night? <-- das stimmt doch nie und nimmer
11)Pinto says he did'nt want any mistakes like last time.
12)He wanted to know whether I visited him again while he was in prison.
