Champagne For One - Plot Summary

Plot Summary

Archie gets a phone call from Dinky Byne, who is expected at a dinner party that night, given by his aunt in honor of four young, unwed mothers. These women have recently left Grantham House, a home where expectant unwed mothers receive support, room and board in the months prior to giving birth.

Dinky wants to beg off the dinner, saying he has a bad cold, and asks Archie to fill in for him. Archie agrees and, chatting with Rose Tuttle after dinner, learns that Faith Usher carries around a vial of cyanide. Apparently Faith wants to have it handy should she ever decide to commit suicide. Rose is worried, and Archie reassures her by promising that he'll see to it that nothing bad happens.

But something bad happens a few minutes later, when Faith suddenly dies, poisoned by cyanide later shown to have been in her champagne. Those present hope that Faith suicided, largely because they hope to avoid notoriety. But Archie had been keeping his eye on Faith and is certain that she put nothing in her glass – therefore, it must have been murder.

Archie comes under pressure from the guests, the police and the Police Commissioner himself to back off his position regarding Faith's death. Meanwhile, Edwin Laidlaw hires Wolfe to see to it that the investigation does not result in the discovery that he is the father of Faith's child. Wolfe agrees to identify and expose the murderer – if there is one – before the police learn of Laidlaw's role in Faith's life.
