There were only four stationers of any consequences in the town, and at each Holmes produced his pencil chips, and bid high for a duplicate. All were agreed that one could be ordered, but that it was not a usual size of pencil and that it was seldom kept in stock. My friend did not appear to be depressed by his failure, but shrugged his shoulders in half-humorous resignation.

“No good, my dear Watson. This, the best and only final clue, has run to nothing. But, indeed, I have little doubt that we can build up a sufficient case without it. By Jove! my dear fellow, it is nearly nine, and the landlady babbled of green peas at seven-thirty. What with your eternal tobacco, Watson, and your irregularity at meals, I expect that you will get notice to quit, and that I shall share your downfall⁠—not, however, before we have solved the problem of the nervous tutor, the careless servant, and the three enterprising students.”

Holmes made no further allusion to the matter that day, though he sat lost in thought for a long time after our belated dinner. At eight in the morning, he came into my room just as I finished my toilet.
