Mark is tied to Jefferson for money, Iris is tied to her sister perhaps (I have only read Sparkling Cyanide once because I disliked it.). and Jerry is tied to his sister since he was invalided perhaps but I have a better answer, Did they all go to London in the Book, Mark to be away from an attempt of Murder, Jerry and he took Megan and perhaps Iris went
If Jerry had met Megan and fallen in love with her in different circumstances he would be Mrs Smyngton's Son-in-law, Mark was related by Marriage to Ruby Keene and Iris was related to the 1st Victim in Sparkling Cyanide and an in-law to the 2nd Victim so they were all or might have been In-laws of the Victims
Mark appears in Body In The Library, Jerry appears in The Moving Finger and Iris Marie is in Sparkling Cyanide, In each case is The Murderer albeit in Iris's Case The Murderer or one of them related to the Murderer?
I meant The Murderer was related to the Victim albeit distantly.
HerculeandAchille are you sure of your Facts? SPOILER ALERT all 3 don't have the same marital status, 2 are single but the other is Married albeit without others knowing
Mrs Blair said:
Did Antony and Iris and/ or Megan and Jerry get married in the books? It's been so long since I read them...No, they didn't. "The moving finger ends with a conversation between Megan and Jerry, in which he says that if she decides not to marry him they will have to return the wedding gifts, and Sparkling Cyanide ends with Anthony telling Iris that they can give away the money she will get from Rosmary's estate - she still doesn't have control of it because she isnt 21 years old or married. Both couples were planning to be married at the end of the books.
Did they have a Deformity for instance did they all have a Limp?
