The Birthday Gathering

A Carefully Pleasant Party
A Celebrated Birthday
Letitia Blacklock arranges a tea party for Dora Bunner, with presents, rich food, and Mitzi’s celebrated cake. The gathering offers Dora affection and attention after a life marked by poverty and disappointment.
A Dangerous Household
Letitia is increasingly aware that the earlier shooting may not be settled. Yet the guests’ ordinary movements through the house create opportunities for someone to tamper with medicine.
The Missing Tablets

A Mislaid Remedy
Dora Searches
Dora Bunner cannot find the aspirin she expects to have brought home. She remembers that there are tablets beside Letitia Blacklock’s bed and goes upstairs to look for them.
A Fatal Substitution
The tablets are not aspirin but poison. Dora takes them without knowing that the bottle has been made dangerous, and the apparent target is Letitia rather than the woman who swallows them.
A Death in Sleep

The Wrong Victim
A Sudden Report
Dora Bunner is found dead in her bed. The doctor suspects narcotic poisoning, and the surviving tablet confirms that the bottle contained something other than aspirin.
A Second Murder Inquiry
Craddock recognizes that the poison was likely placed for Letitia. Dora’s death shows that the killer is willing to use an indirect method and that the threat remains active.
The Kindly Birthday

Kindness as Cover
A Misleading Gift
Jane Marple interprets the elaborate birthday as part of the emotional logic of the murder. The killer gives Dora a happy day while arranging a death that can be mistaken for a medication error.
A Chosen Appearance
The poisoned aspirin was placed by Letitia’s bed so suspicion would fall on an attempted murder of Letitia. The arrangement transforms apparent tenderness into a means of concealment.
A Pattern of Elimination

The Second Crime Connects
One Threat, Several Victims
The poisoning links the original shooting to a continuing effort to protect a secret. It cannot be explained as an accident once the hidden door and the identity clues are considered together.
Danger Narrows
Dora’s death also makes the household’s daily routines part of the evidence. The killer has knowledge of where Letitia keeps her medicine and how Dora might reach it.
