Trevor Stern was not a popular man, in spite of his wealth. He (live) in a large house about a mile outside the village of Prenton. When he (find) dead in his studio, no one (cry), not even his only daughter. It was soon clear that he (murder).

Detective Inspector Blackledge took statements from his widow, Dorothy, his seventeen-year-old daughter, Lucy, his business partner, Gerald Brook, and his doctor.

Dorothy: "I (not love) my husband, he was a cold and selfish man. But I (not murder) him, either. After dinner last night he said he (want) to check some business papers in his study. He (have) a meeting with Gerald, his business partner, the next morning. He (ask) for some tea. That was about 9 o'clock. I (watch) a rather exciting film on television, So I (tell) Lucy to take it to him. At quarter past nine Doctor Emerson (call). I noticed the time because we (expect) him to come earlier. I (answer) the front door bell. Trevor (still shout) in his study. He and Lucy (obviously have) a serious row. So I (take) the doctor into the sitting-room for a moment. Then Trevor stopped shouting. I guessed Lucy (go) out by the back door. Doctor Emerson (go) to the study. I think he (want) to persuade Trevor to go to the hospital for some tests, but Trevor (not want) to go. I (hear) him shouting again several times over the next twenty minutes. He (call) him an ignorant country doctor, and later he (say) something like 'There's nothing you can do!' I think Lucy (come) into the house while the doctor (still talk) to Trevor. I (hear) the front door bang during a quiet few seconds when Trevor (not shout). I was tired and fed up and went to my bedroom soon after that. My sister (phone) and we (talk) for ages. I (tell) her I (decide) to leave Trevor."

Lucy: "Mum (watch) some stupid film after dinner, so she (make) me take Dad's tea into his study. It was about nine o'clock. He was in a really mean mood. He shouted at me because I (spill) a few drops of tea on his desk while I (pour) it. I (not want) to watch the film so I (creep) out by the back door. I (decide) to go down to the village and use the public phone to call Alan. He's my boyfriend. I (never like) Mum or Dad to be around when I (talk) to him. Especially yesterday, because Dad and I (have) a stupid argument about Alan the day before. It (normally take) quarter of an hour to walk to the village. Perhaps it (take) me less time last night. I can't prove I (go) to the village. No one (see) me when I (walk) into the village. I (see) Gerald, that's Dad's business partner. He (stand) near the window in his sitting-room. He (not see) me, though, because it was dark outside. he (talk) on the phone, I think.
Alan (not answer) the phone. Then I (remember) he (tell) me he was playing in a concert that evening. So I (walk) home again. I (meet) Gerald just before I (reach) our house. He (look) for his dog. That was about twenty to ten. I came in by the back door as quietly as possible and went to bed. I didn't want to see my parents again that evening."
