Love or money - Beatriz, Daniela and Giovana

On Monday, Sergeant Foster went to Roger's office and asked some questions. Then he went to Albert's house and asked some more questions. Inspector Walsh sat in his office and telephoned. He made phone calls about Tom Briggs. After that he had some coffee and some sandwiches .
At three o'clock the two detectives drove to the Clarkson's house.
'We would like to see everyone ', they told Roger.
Everyone came into the living room and sat down.
Inspector Walsh stood in front of the windows and looked at them, one by one:
' I want to talk to you. Someone put sleeping tablets in her hot milk and killed her. Nobody wanted to tell me the true story but now that I know I'm going to tell you ! '
The inspector looked at Albert: ' Mr . King your wife is very ill and needs a nurse. You told me this. You didn't tell me about your house. You're selling your house next month because you need money. '
Albert was angry. ' Last year I asked Molly's husband for some money, and he said yes. But then he died in an accident. '
' Accident! 'Diane cried. ' That was no accident. Mother killed Daddy because she wanted his money.'
' Let's talk about you now, Diane,' Said Walsh. Last month you took money for television. This month she gave money for your telephone. Every month you asked your mother for more money. "It was no accident, she killed Daddy. I'm going to tell the police. "Your mother was afraid of the police and so she gave the money. But in the end she wanted to stop you. She told doctor Pratt 'No more money' on Thursday and on Saturday she died. You took hot milk to your mother, what did she tell you ?
Diane began to cry. 'I loved Daddy. He always gave me money, he loved me. It was mother, she didn't love Daddy, and she didn't love me. ' Diane stopped. ' It was true, I took a lot of money from mother. On Saturday, she told me. "NO MORE MONEY." I wanted to kill her, but I didn't.
Inspector Walsh looked at Roger. 'Mr Clarkson also needed money.'
Roger's face went red. ' Don't tell them! Please! '
' Mr. Clarkson lost his job lat month. He has no money, but he has an expensive house and an expensive car . He likes expensive things.'
' It's doesn't matter now! 'Diane said. 'Mother is dead and we have a lot of money. You don't need a job now. '
Inspector Walsh began again . 'Peter Hobbs is a very angry young man. Mrs Clarkson was not very nice to him. He got sleeping tablets from the shop. But he did he put the tablet in the hot milk? I don't think so.'
' Tom Briggs wanted half the garden for his farm. He was in the kitchen last night. Did he put the tablets in the hot milk? I don't think so.'
Inspector Walsh moved away from the window, and sat down. ' I'm going to tell you the true story now.'
' Everyone needed the money. Everyone. But neither Jackie nor Diane, neither Peter nor Tom or Roger killed Molly.'
Everybody was quiet and confused.
'Look at this ':

Dear Family,
I was tired of my life and tired of all of you keep asking me for money. I was feeling like someone was threatening me and I was afraid and sad.
I was tired and with a lot of anger inside, so I found a solution to go out of this and this was the only way that I found...killing myself.
I leave this letter to make it clear that I killed myself. I hope you all understand.
I loved you all .
Goodbye forever
Molly

' We found this letter in the pocket of Roger's pijama's . He put the tablets in Diane's bag to blame her. He did that to get more money. Come on, you are arrested!' Said Walsh.
