He tried to raise his arm, but it was helpless. Sholmes felt it, gently at first, then in a rougher way, “to see how badly it was hurt,” he said. He concluded that Wilson was really hurt, so he led him to a neighboring pharmacy, where a closer examination revealed the fact that the arm was broken and that Wilson was a candidate for the hospital. In the meantime they bared his arm and applied some remedies to ease his suffering.
“Come, come, old chap, cheer up!” said Sholmes, who was holding Wilson’s arm, “in five or six weeks you will be all right again. But I will pay them back ... the rascals! Especially Lupin, for this is his work ... no doubt of that. I swear to you if ever——”
He stopped suddenly, dropped the arm—which caused Wilson such an access of pain that he almost fainted—and, striking his forehead, Sholmes said:
“Wilson, I have an idea. You know, I have one occasionally.”
He stood for a moment, silent, with staring eyes, and then muttered, in short, sharp phrases:
“Yes, that’s it ... that will explain all ... right at my feet ... and I didn’t see it ... ah, parbleu! I should have thought of it before.... Wilson, I shall have good news for you.”
Abruptly leaving his old friend, Sholmes ran into the street and went directly to the house known as number 25. On one of the stones, to the right of the door, he read this inscription: “Destange, architect, 1875.”
There was a similar inscription on the house numbered 23.
Of course, there was nothing unusual in that. But what might be read on the houses in the avenue Henri-Martin?
A carriage was passing. He engaged it and directed the driver to take him to No. 134 avenue Henri-Martin. He was roused to a high pitch of excitement. He stood up in the carriage and urged the horse to greater speed. He offered extra pourboires to the driver. Quicker! Quicker!
