Jack and Sue went to question Charlton's daughter in the house of the family in the outskirts of Washington. A blonde woman around 30 answered the door.

- Elise Charlton? Jack Hudson, FBI. She is my colleague, Sue Thomas. We have to ask you a few questions about your father.

- Of course… come in – Elise said. Her red-rimmed eyes and indifferent look indicated clearly that the past few days had extremely broken her.

- Could you talk about your family? What kind of a person was your father? – Sue asked, after they sat down in the living-room.

- Our relationship was very good… we were really close to each other, I could talk to him about everything. He was a kind man, but since he used to be a soldier, he knew how to be hard, in order to get what he wanted.He is from South Carolina, but we moved to Washington when I was a child. My mother had been seriously ill for years and died after a long suffering a few years ago. As an effect of the tragedy, my father was in depression for a long time, therefore I moved home to be with him in those hard times. Since then we had been living here together.

- Do you know about anyone who could have had a motive for murdering Mr. Charlton? Did your father have enemies? – Jack asked.

- He may have had some at the time when he was a soldier... But since we have been living here, I don't know about such people. As far as I know, he didn't have serious problems with anyone in Washington… and I don't know his mates from South Carolina. But my father wrote down all important events… as far as I can remember, he kept a diary every year.

- Could we see your father's diaries from the past few years? – Sue asked.

- Just a minute – the woman replied, and headed towards her father's room. She returned with lots of diaries soon.

- He always kept them in his room… no one else has ever read them… He wrote down all important events of his life… Maybe even those I have never heard about… - she said silently, looking at the diaries in her hand.

- We have to take these with us – Jack said. – We may learn important information from these, which can help us find the murderer of your father.

- Of course… but I would like to get them back… these are almost the only things which mean a connection to my father … – Elise whispered. – I haven't had enough strength to read them yet… his death hurts so much...

- We'll bring them back to you as soon as possible – Sue reassured her. – Thank you for your help.

Sue and Jack stepped out of the house and headed towards the home of Konrad's wife.

- I hope the diaries will help us answer the unanswered questions… – Sue said, when they got into their car.

Half an hour later Sue and Jack arrived to Konrad's house. A woman in her fifties with greyish hair came to open the door.

- Mrs. Konrad? FBI, we would like to ask you a few questions about your husband.

- Come in – the woman said surprised, and led them into the living-room.

- We learnt that your husband wasn't born in the US. Is this true? – Jack asked.

- My husband was German… We lived in Germany in the first years of our marriage, and moved to Washington after that.

- Do you have any idea who could have murdered your husband?

- When he was a soldier, he had serious quarrels with several of his mates. Sometimes they didn't even talk to each other, but eventually, things were always settled.Always… except for one person. That man hated my husband, he tried to cause Walter as much harm as he could...

- Do you know what could be the reason for this? – Sue asked.

- My husband didn't talk much about this… But sometimes he told me a few things… and also mentioned the case in a few letters he wrote to his friends… I didn't really understand what he was referring to… He wrote he knew everything was his fault, but remedied it as much as he could, and the others forgave him after this… except for this man…

- Did your husband ever talk about what he did which had such consequences?

- No… he only said he was sorry for what he had done and did everything possible to make it right… There wasn't any reference to this in his letters either… - Mrs. Konrad couldn't hold her tears back. – I miss him too much… since I got to know that he had died, I'm looking at his photos and reading his letters, to ease his absence…

- Could you tell the name of the person with whom he had such a bad relationship?

- If I remember right, he said Derek Jenkins… my husband said something about Jenkins' mother being German and his father American… Jenkins and my husband served in Germany, then both came back to the States… I don't know anything more about him.

- Was your husband in contact with his mates from the army?

- He was with some of them… They met from time to time… he corresponded regularly with some of them… and also kept in touch with some of his friends in Germany.

- Can we see those letters? – Jack asked.

- I'll bring them in a moment… - Mrs. Konrad replied. – She went to her room, and returned with lots of letters a few minutes later.

- We have to take these with us… - Jack said. – They may help us find the murderer of your husband. Of course, you'll get them back as soon as we have closed the case and sent the murderer to prison.

- These are the only things left from my husband… - Mrs. Konrad said in tears. – Please, bring them back to me as soon as possible.

- We will do just that – Jack assured her.

- Don't worry – Sue put her arm on the woman's shoulder to calm her. – We'll find the murderer of your husband and put him to prison for the rest of his life.

- Thank you for your time, you have helped a lot – Jack said.

Sue and Jack left the house and headed back towards the bullpen.
