Well, we know what happened next.
As soon as the lights went and everyone was exclaiming, she slipped out through the previously oiled door and up behind Rudi Scherz who was flashing his torch round the room and playing his part with gusto.
I don't suppose he realised for a moment she was there behind him with her gardening gloves pulled on and the revolver in her hand.
She waits till the torch reaches the spot she must aim for - the wall near which she is supposed to be standing. Then she fires rapidly twice and as he swings round startled, she holds the revolver close to his body and fires again.
She lets the revolver fall by his body, throws her gloves carelessly on the hall table, then back through the other door and across to where she had been standing when the lights went out.
She nicked her ear - I don't quite know how -"
"Nail scissors, I expect," said Miss Marple.
"Just a snip on the lobe of the ear lets out a lot of blood.
That was very good psychology, of course.
The actual blood running down over her white blouse made it seem certain that she had been shot at, and that it had been a near miss."
"It ought to have gone off quite all right," said Craddock.
"Dora Bunner's insistence that Scherz had definitely aimed at Miss Blacklog had its uses.
Without meaning it, Dora Bunner conveyed the impression that she'd actually seen her friend wounded.
It might have been brought in Suicide or Accidental Death.
And the case would have been closed.
That it was kept open is due to Miss Marple here."
"Oh, no, no." Miss Marple shook her head energetically.
"Any little efforts on my part were quite incidental.
It was you who weren't satisfied, Mr. Craddock.
It was you who wouldn't let the case be closed."
"I wasn't happy about it," said Craddock.
"I knew it was all wrong somewhere.
But I didn't see where it was wrong, till you showed me.
And after that Miss Blacklog had a real piece of bad luck. I discovered that that second door had been tampered with.
Until that moment, whatever we agreed might have happened - we'd nothing to go upon but a pretty theory.
But that oiled door was evidence. And I hit upon it by pure chance - by catching hold of a handle by mistake."
"I think you were led to it, Inspector," said Miss Marple.
"But then I'm old-fashioned."
"So the hunt was up again," said Craddock. "But this time with a difference. We were looking now for someone with a motive to kill Letitia Blacklog."
"And there was someone with a motive, and Miss Blacklog knew it," said Miss Marple.
"I think she recognised Phillipa almost at once.
Because Sonia Goedler seems to have been one of the very few people who had been admitted to Charlotte's privacy.
And when one is old (you wouldn't know this yet, Mr. Craddock) one has a much better memory for a face you've seen when you were young than you have for anyone you've only met a year or two ago.
Phillipa must have been just about the same age as her mother was when Charlotte remembered her, and she was very like her mother.
The odd thing is that I think Charlotte was very pleased to recognise Phillipa.
She became very fond of Phillipa and I think, unconsciously, it helped to stifle any qualms of conscience she may have had.
She told herself that when she inherited the money, she was going to look after Phillipa. She would treat her as a daughter.
Phillipa and Harry should live with her.
She felt quite happy and beneficent about it.
But once the Inspector began asking questions and finding out about 'Pip and Emma' Charlotte became very uneasy.
She didn't want to make a scapegoat of Phillipa.
Her whole idea had been to make the business look like a hold-up by a young criminal and his accidental death. But now, with the discovery of the oiled door, the whole viewpoint was changed.
And, except for Phillipa, there wasn't (as far as she knew, for she had absolutely no idea of Julia's identity) anyone with the least possible motive for wishing to kill her.
She did her best to shield Phillipa's identity. She was quickwitted enough to tell you when you asked her, that Sonia was small and dark and she took the old snapshots out of the album, so that you shouldn't notice any resemblance, at the same time as she removed snapshots of Letitia herself."
"And to think I suspected Mrs. Swettenham of being Sonia Goedler," said Craddock disgustedly.
"My poor Mamma," murmured Edmund.
"A woman of blameless life - or so I have always believed."
"But of course," Miss Marple went on. "It was Dora Bunner who was the real danger.
Every day Dora got more forgetful and more talkative.
I remember the way Miss Blacklog looked at her the day we went to tea there.
