In the Teeth of Adversity — Marian Babson

A dentist's office becomes a crime scene: “Uproarious . . . a hilarious cast of characters . . . sparkling comedy” (Publishers Weekly).
 
Endicott Zayle is a dentist to the rich and famous -- as well as to public relations partners Doug Perkins and Gerry Tate. Now, he desperately needs their help. It looks like his use of an experimental anesthetic has come back to bite him, and a beautiful model lies dead in his dentist's chair.
 
There may be more to the story, though -- and Perkins and Tate, with Pandora the cat at their side, will have to fill in the missing pieces in this rollicking mystery from an Agatha Award winner praised for her “very funny dialogue” (The New York Times Book Review).
