この場面を読み終えました

ホームズは「パイプ三服ぶんの問題だ」と言い、椅子の上で体を丸めて黙って考え込む。ワトソンもうとうとし始めたころ、ホームズは急に跳び起き、午後のサラサーテの演奏会に行かないかと誘う。
"To smoke," he answered. "It is quite a three pipe problem, and I beg that you won't speak to me for fifty minutes." He curled himself up in his chair, with his thin knees drawn up to his hawk-like nose, and there he sat with his eyes closed and his black clay pipe thrusting out like the bill of some strange bird. I had come to the conclusion that he had dropped asleep, and indeed was nodding myself, when he suddenly sprang out of his chair with the gesture of a man who has made up his mind and put his pipe down upon the mantelpiece.
「たばこを吸うのさ」と彼は答えた。「これはまさしくパイプ三服ぶんの問題だから、五十分ほどは話しかけないでくれたまえ」彼は椅子の上で体を丸め、細いひざを鷹のような鼻先まで引き寄せると、目を閉じ、黒い陶製のパイプを奇妙な鳥のくちばしのように突き出して、じっと座っていた。彼は眠りこんでしまったのだろうと私は思い、実のところ自分もこっくりしかけていたが、そのとき彼は、心を決めた人のような身ぶりで不意に椅子から跳び起き、パイプを炉棚に置いた。
"Sarasate plays at the St. James's Hall this afternoon," he remarked. "What do you think, Watson? Could your patients spare you for a few hours?"
「今日の午後、セント・ジェイムズ・ホールでサラサーテが弾くんだ」と彼は言った。「どうだい、ワトソン?きみの患者たちは、二、三時間ほどきみを放免してくれそうかね?」
