Third Girl by Agatha Christie

4.0

A distraught young woman comes to see Poirot because she thinks she's committed a murder, but flees before he can find out any details. But how did she hear of him? And how can she not be sure if she's killed someone? With a story like that, Poirot's got to get involved, and with the help of his quirky friend, the mystery writer Ariadne Oliver, he untangles a sinister mystery.

I love Christie's self-insert character Ariadne Oliver (who complains about the popularity of her Finnish detective Sven Hjerson, a character she has come to loathe.) This novel also brings back Dr. Stillingfleet, last seen in short story "The Dream," as well as the mysterious, efficient investigator Mr. Goby from After the Funeral. We see signs of Poirot's age being somewhat retconned, since he would have had to be of an advanced age indeed if he had retired after World War I.

Highly recommended; although the plot seems a bit dated today, it's still a fun read.
