Doctor: "I (call) at the Sterns' house at nine-fifteen. I was rather later than I (plan) to be because I (visit) another patient. When Mrs Stern (let) me into the house she (seem) rather embarrassed and (show) me into the sitting-room. I could hear Trevor Stern (shout) at someone in his study. Mrs Stern said something about teenage girls and that they (have) problems with Lucy. Well, the shouting (stop) almost immediately, so I (go) to his study. Lucy (already leave) the room before I (get) there. I (try) to explain to Trevor why he needed to have these hospital tests, but he (not let) me. He said I was an ignorant country doctor who (not know) what he (talk) about. I (realise) it was no use arguing with him so I (leave) 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 (not be) really friends. Yes, my house (be) just around the corner from the Sterns'. I (live) here for two years now. I (have) a little cottage in the village. But I (buy) this house when I (start) to earn a lot of money.
I can't really tell you very much about the night Trevor (die). I (take) my dog for a long walk that evening. I (go) up on the hills, away from the village. Then the stupid dog (go) after a rabbit or something and I (lose) him in the dark. I (look) for him when I (meet) Lucy, as a matter of fact. She (walk) up the road towards their house. She (seem) rather upset. I asked her if she (see) the dog, but she said she (not have). She (go) into her house and I (find) 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 (you think)? Who (kill) Stern?"

Ross: "I don't know. It (not be) his wife. She (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 (find) 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 (mean) he (leave) the Sterns' house before half past nine."

Ross: "Exactly."

Blackledge: "Anyway, Dorothy Stern told her sister she (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 [?] to the village and back if he [?] her at twenty to ten. She [?] at be her father at nine-fifteen."

Blackledge: "But look at all the statements. The times (not quite fit)."

Ross: "Neither do the facts. Someone (tell) lies."

Blackledge: "I (think) it's time we (make) an arrest."
