You've finished this scene

Holmes reveals that he wanted to inspect the assistant’s knees, not his face, and found exactly what he expected. He refuses to explain the tapping of the pavement, insisting that they must observe before discussing conclusions. Together they walk around the corner to examine what lies behind Saxe-Coburg Square.
"Not him."
「彼じゃないよ」
"What then?"
「じゃあ、何を?」
"The knees of his trousers."
「ズボンのひざさ」
"And what did you see?"
「それで、何が見えたんだい?」
"What I expected to see."
「思っていたとおりのものさ」
"Why did you beat the pavement?"
「どうして歩道を叩いたんだい?」
"My dear doctor, this is a time for observation, not for talk. We are spies in an enemy's country. We know something of Saxe-Coburg Square. Let us now explore the parts which lie behind it."
「いいかね、先生、今は観察するときで、おしゃべりをするときではないよ。私たちは敵地に入り込んだスパイなんだ。サックス・コバーグ・スクエアのことは、いくらか分かった。今度はその裏手を探ってみよう」
