Lord Edgware Dies  - Agatha Christie

"Did Miss Adams know any doctors? I mean, was any particular doctor a friend of hers?"

Jenny shook her head.

"Another question. Did Miss Adams wear pincenez?"

"Glasses? Never."

"Ah!" Poirot frowned.

A vision rose in my mind. A doctor, smelling of carbolic, with short-sighted eyes magnified by powerful lenses. Absurd!

 

I love how Hastings is going off on a tangent every once in a while.
