jennifer

Do we have a correct answer yet?  I agree with Body in the Library.  Mrs. Blair, you can tell us the winner any time.  thanks!

Mrs Blair

No winner yet!

Mrs Blair

I don't understand how you guys got The body in the Library from the clues...

lachy.a.w

A couple of the clues fitted so I just took a guess

LL88

Is it "And Then There Were None"? Each of the clues may be present in it, although some a little warped...

Mrs Blair

No, I'm afraid not.

Tommy_A_Jones

Hercule Poirot's Christmas,

Mrs Blair

No

Tommy_A_Jones

Towards Zero

LL88

Yes, I also thought about the last two which Tommy_A_Jones suggested. If it is not "->0", then I have no more ideas.

Mrs Blair

No it is not towards zero. I can't see how the clues fit that one either! I keep checking what I wrote!

Tommy_A_Jones

Dead Man's Mirror

Mrs Blair

Not heard of that novel.

Tommy_A_Jones

Sorry forgot it was a Novel How about Cards On The Table

Mrs Blair

No, right I am giving you all another clue to stop the random guessing hopefully.
Next clue: plant.

Sad_Cypress

Murder At The Vicarage?...

Mrs Blair

Yippee! Yes, well done! Sad cypress to go next!

Sad_Cypress

Oh! Well I'll try!

I think this will be an easy one :

Matches, water, horse, tea

Zeddie

Is it The Hollow?

Veroinca Cray calls to borrow a box of matches. 

John Cristow is found bleeding into the water in the swimming pool and Henrietta Savernake drops the gun into the water apparently by accident.

Henrietta hides the real gun that was used to kill John in a sculpture of a horse.

Gerda drinks the poisoned tea she had brewed to kill Henrietta by mistake and kills herself.
