Canon: The Blue Carbuncle (BLUE)
Title: Cubic Capacity
Author: ennui_enigma
POV: Watson
A/N: Prompted by Holmes’ bold statement that starts off this narrative.

“It is a question of cubic capacity,” said he; “a man with so large a brain must have something in it.”

I shook my head.

The following day I offered him a large bowler hat. “Pray, what do you infer?”

Holmes deposited it upon his head. “What an enormous cerebrum,” he exclaimed. “Undoubtedly a genius!”

“Not a genius, Holmes. A patient with hydrocephalous.”

Holmes was silent as he thoughtfully removed the hat. “Well done, Watson,” he said with a rueful smile.
