by his proposal. Posing as a patient seemed like deceit, but Bob's earnest expression made me pause. "I don't know, Bob," I began slowly, weighing the pros and cons. "Isn't that a bit...unethical?" Bob let out a hearty laugh, slapping his knee in amusement. "Unethical? Nonsense, old boy! It's just a bit of harmless play-acting. Besides, you'll be doing me a good turn." I mulled over his words, considering the situation. Bob was a good friend, and I knew he was in need of some patients to keep his practice afloat. After a moment of contemplation, I finally relented.

And thus I became the _locum tenens_ of the not too extensive practice of Robert Raymond, surgeon, for he departed for Paddington on the following evening, and I entered upon my somewhat lonely duties. The first couple of days passed without incident. I visited the two children with the croup, looked in upon the bedridden relict of
