"Then there was a hard brown lozenge called the Tonsil Tickler. The Tonsil Tickler tasted and smelled very strongly of chloroform. We had not the slightest doubt that these things were saturated in the dreaded anaesthetic which, as Thwaites had many times pointed out to us, could put you to sleep for hours at a stretch.

"Yes," we said, "but why sell them to children?"
"It's a plot," Thwaites said. "A grown-up plot to keep us quiet.
