Mrs. Stevenson tried to call her husband at work, but instead has just been connected with the wrong number and can hear two men talking about a suspicious plot. She tries to figure out who she is talking to but they can't hear her. This is one of the men talking. (A guy named George)
"Is everything OK? Is the coast clear fortonight?"
Mrs. Stevenson hears the men talking about a murder plan. She wants to try to call back the unknown number to find out more and inform authorities. She is talking to the operator trying to figure out what to do.
"I know it was a wrong number and I had no businesslistening -- but these two men -- they were cold-blooded fiends-- and they are going to murder somebody "
Mrs. Stevenson calls the police to tell them about the plans she overheard, because the operator wouldn't trace the call. She is worried and scared and demanding. She wants something to be done immediately.
"Police Department? This is Mrs. Stevenson. I'm calling to report a murder. I mean -- the murder hasn't been committed yet. I just overheard plans for it over the telephone. Over a wrong number"
The police did not believe Mrs. Stevenson and she starts to panic and break down. Her phone keeps ringing but every time she picks up, no one talks or does anything. She is home alone and an invalid and she starts to freak out.
"Hello? Hello ... Oh, for heavens sake -- who is this? Hello -- hello. HELLO."
Mrs. Stevenson is trying to call someone to come over (a trained nurse) when she hears a click and realises someone is in her house and she is about to be killed. She is scared and panicking.
"That click just now as though someone had lifted the receiver off the hook off the extension telephone downstairs. There's someone in this house and they're listening to me now."
George has killed Mrs. Stevenson under request. While she was killed Mrs. Stevenson was dialing the police so they were on the phone when George said everything was ok.
"Eh, er, police department? Oh, I’m sorry. Must havegot the wrong numbah. Don’t worry. Everything’s OK."
