I ... (call) at the Sterns' house at nine-fifteen, I ... (be) 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 shouting at someone in his study. Mrs Stern ... (say) 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 ... (need) to have these hospital tests, but he ...
(not/let) me. He ... (say) I ... (be) an ignorant country doctor who ... (not/know) what he ...
(talk) about. I ... (realize) it ... (be) no use arguing with him so I ... (leave) after only a few
minutes. I ... (be) quite angry actually. I ... (let) myself out of the house without seeing
Lucy or Mrs. Stem.
Yes, Trevor ... (be) my business partner. We ... (not/be) really friends. Yes, my house
... (be) just round 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) earning 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 ... (ask) her if she ... (see) the dog, but she ... (say) she
... (not). She ... (go) into her house and I ... (find) him a few minutes afterwards, I ... (be)
back home by just after quarter to ten.
Detective Inspector Blackledge ... (show) the statements to her colleague, Sergeant
Ross.
BLACKLEDGE: Well, Ross. What you ... (think)? Who ... (kill) Stern?
ROSS: I ... (not know). It ... (not/be) his wife. She ... (not/even/go) into the study.
BLACKLEDGE: But she ... (admit) she ... (not love) him. You ... (think) she ... (be) in
love with the doctor?
ROSS: It ... (be) possible. And perhaps Trevor Stern ... (find out). But we ... (know)
the doctor ... (be) at the hospital by ten o'clock that night. And that ... (be) at least half an
hour from the Sterns' house.
BLACKLEDGE: But that ... (mean) he ... (leave) the Stems' house before half past
nine.
ROSS: Exactly.
BLACKLEDGE: Anyway, Dorothy Stern ... (tell) her sister she would leave her
husband. She ... (not need) murder him.
ROSS: But what about Lucy?
BLACKLEDGE: Yes, there ... (be) something about Lucy's story which doesn't quite
fit. Let's see, what did Gerald Brook say?
ROSS: That's it! Lucy ... (not/walk) to the village and back, if he ... (meet) her at
twenty to ten. She ... (still/shout at) by her father at nine-fifteen.
BLACKLEDGE: But look at all the statements. The times don't fit.
ROSS: Neither do the facts. Someone ... (tell) lies.
BLACKLEDGE: I think it's time we ... (make) an arrest.
