Our view
“Third Girl” is a late Poirot novel that draws real warmth from teaming the detective with the crime writer Ariadne Oliver. Some readers note that the mystery takes its time and the murder comes late, yet they are pleased with the solution. Others object to dated observations and hasty romances. Admirers of Poirot will enjoy watching the two work together again.
