Chapter 14: Sleuth interviews Nannie, Suspect 6, and Suspect 10. Critical piece of evidence is introduced but overlooked. Suspects 1, 4, and 5 are dismissed. Finger points to Suspects 1 and 7.
Sleuth meets Nannie who hints that Josephine is always listening at doors and writing in a book – another hint that there is a diary to be found. No one thinks to look at it. But it is the damning piece of evidence at the end.
Sophia states she thinks Suspect 8 Eustace hates them all. She also states that her mother Suspect 3 Magda loves drama and gets bored and likes to stir things up.
Sleuth considers Suspect 2 Philip, his fiancee’s father is the only one who has avoided him. Considers his motive: he was cold, reserved, a jealous second son. Could he have wanted his brother to fail enough to kill their father to incriminate the brother? The whole family wanted it to be Suspects 1 and 7, Brenda and Laurence, but no one seemed to really believe it. He investigates the bathroom where the insulin was kept. Anyone could have had easy access to it.
An outsider was given a sealed envelope from the Victim which he was to forward to the attorney upon the Victim’s death. It is a will written by hand. The will leaves a bequest to Suspect 1 and the rest to Suspect 6 Sophia, presenting his fiancée with a motive if she had known about it. Victim did not consider his sons fit to take his place.
Suspect 9 is nearly killed by her own device. Sleuth feels guilty for not protecting her. Everyone knew she played there. Important clue: someone stood on a broken chair with muddy feet and Josephine was the only one short enough to need the chair to plant the object that nearly falls on her head. But this is not considered by the sleuth until the end.
She was always snooping and writing things in a little black book. They decide to look for it. They search her room. It was in disarray as if someone had searched it. Anyone could have done it. Sleuth remembers she was in the cistern room. He goes there and finds a packet of letters from Suspect 1 Brenda to Laurence. Evidence convicts Suspects 1 and 7.
The attempt on Suspect 9 Josephine suggests the murderer does not like direct violence which is why he or she used poison and a booby trap. They dismiss Suspect 1 Brenda based on the assumption that she could not have rigged the booby trap. It must have been Suspect 7 Laurence.
The inquest is held, the contents of the will are revealed. It divides the family. Josephine was in the hospital, so she missed the drama.
Suspect 6 Sophia is sending Eustace and Josephine off to school. She is letting Laurence go. Suspects 1 and 7 Brenda and Laurence are arrested. Sophie reveals that she had known about the will.
Josephine returns. She points the finger at Laurence for the attempt on her life. Said she saw him coming out of the cistern room one day and found the letters he hid in there.
Letters were damning but the defense will twist it to say they were talking about being together after the Victim died of natural causes. Their instincts still place doubt on their guilt. They review the motives. Sleuth realizes that he thought the child’s room was searched for the letters, but she didn’t have or hide the letters. So someone must have been looking for her little black book. Receives the news that the Nannie has been killed.
Roger and Clemency are on their way out. They deny that they had motive to kill Josephine or Nannie. Josephine states that she never liked Nannie. Josephine tells the Sleuth that she knows who poisoned her grandfather, set up the booby trap, and put poison in her cocoa. She refuses to tell. Nannie was killed with the digitalin that Edith takes. Edith takes Josephine to London.
They get the news that Suspects 10 and 9 Edith and Josephine were found dead in the car that had gone off the road into a quarry. The sleuth remembered that he had seen Edith write letters and left them in the hall. He retrieves them.They realize Edith was protecting Josephine. Her little black book is in the second envelope.
They read the little black book and recognize the signs they missed. The sleuth and Sophia decide to marry despite the madness of her sister.
