I have to remember sometimes that The Complete Casebook of Herlock Sholmes is a British book, so I don’t recognize all of the food mentioned in the book. I certainly never would have guessed when I started “The Mystery of the Dustbin” what a winkle was.

Winkle – a small mollusk with spiral shell

Usage: Mr Horatio Smiff never wasted the winkle. He was framed!
