Doctor: «I called at the Sterns’ house at nine-fifteen. I was rather later than I had planned to be because I visited another patient. When Mrs Stern let me into the house she seemed rather embarrassed and showed me into the sitting-room. I could hear Trevor Stern was shouting at someone in his study. Mrs Stern said something about teenage girls and that they had problems with Lucy. Well, the shouting stopped almost immediately, so I went to his study. Lucy had already left the room before I got there. I tried to explain to Trevor why he needed to have these hospital tests, but he did not let me. He said I was an ignorant country doctor who did not know what he was talking about. I realised it was no use arguing with him so I left after only a few minutes. I was quite angry actually. I let myself out of the house without seeing Lucy or Mrs Stern.»Gerald: «Yes, Trevor was my business partner. We were not really friends. Yes, my house is just around the corner from the Sterns’. I have been living here for two years now. I have a little cottage in the village. But I bought this house when I started to earn a lot of money.I can’t really tell you very much about the night Trevor died. I took my dog for a long walk that evening. I went up on the hills, away from the village. Then the stupid dog went after a rabbit or something and I lost im in the dark. I was looking for him when I met Lucy, as a matter of fact. She was walking up the road towards their house. She seemed rather upset. I asked her if she had seen the dog, but she said she did not have. She went into her house and I found him a few minutes afterwards. I was back home by just after quarter to ten.»Detective Inspector Blackledge showed the statements to her colleague, Sergeant Ross.Blackledge: «Well, Ross. What do you think? Who killed Stern?»Ross: «I don’t know. It was not his wife. She did not even go into the study.»Blackledge: «But she admits she didn’t love him. Do you think she’s in love with the doctor?»Ross: «It’s possible. And perhaps Trevor Stern found out. But we know the doctor was at the hospital by ten o’clock that night. And that’s at least half an hour from the Sterns’ house.»Blackledge: «But that means he left the Sterns’ house before half past nine.»Ross: «Exactly.»Blackledge: «Anyway, Dorothy Stern told her sister she would leave her husband. She didn’t need to murder him.»Ross: «But what about Lucy?»Blackledge: «Yes, there’s something about Lucy’s story which . Let’s see, what did Gerald Brook say?»Ross: «That’s it! Lucy went to the village and back if he saw her at twenty to ten. She was at be her father at nine-fifteen.»Blackledge: «But look at all the statements. The times do not quite fit.»Ross: «Neither do the facts. Someone told lies.»Blackledge: «I think it’s time we make an arrest.»
