From I'm Nova – Freudian slip.
Holmes tipped the station porter generously, then hastily climbed up into the hansom, rubbing his gloved hands to warm them. Bath was even colder than London at this time of year, he was already regretting accepting this late case. "Well, come on, Watson! You wrote the address down for our hotel, didn't you?"
"Yes, yes, just a moment." Watson dug his notebook out of his coat pocket, turned to the right page, then burst out laughing. "Oh dear!"
"What is it?"
"No, don't look, Holmes, it's too embarrassing." Watson leaned up and called to the driver, "Sheridan House, 14 North Parade, my good man."
But Holmes had seized his chance, and the notebook, fending Watson off as he scanned the page. "14 North Pole?"
"Well, I did write it in rather a hurry, if you recall," Watson grinned sheepishly.
Holmes snickered, patting his blushing friend on the shoulder. "Don't worry, Watson, we should be back in London long before Father Christmas arrives."
A/N: Inspired by a street sign in my home town. 'North Pde' does look awfully like 'North Pole' from a distance.
