lodger

An anomaly which often struck me in the character of my friend Sherlock Holmes was that, although in his methods of thought he was the neatest and most methodical of mankind, and although also he affected a certain quiet primness of dress, he was none the less in his personal habits one of the most untidy men that ever drove a fellow-lodger to distraction.

As we made our way to the hospital after leaving the Holborn, Stamford gave me a few more particulars about the gentleman whom I proposed to take as a fellow-lodger.
