( のワトソンに初( めて会( った時( 、握手( しただけで、彼( が軍医( でアフガンに行( ってた事( を見( 抜( いてしまったんだ…」- “The first time he met his assistant Watson, Holmes could tell just from a handshake that he was a military doctor who had been stationed in Afghanistan...”
Key Points
握手
( しただけで = just by shaking hands握手
( is the noun “handshake”; adding した makes it the completed action “shook hands”.だけで means that this one action alone was enough as the basis for Holmes’s deduction.
The long 事
( を phrase is what Holmes saw through彼
( が軍医( でアフガンに行( ってた事( means “the fact that he was a military doctor and had been to Afghanistan”.事
( を turns that whole statement into the object of 見( 抜( いてしまった.
行
( ってた and 見( 抜( いてしまった are casual narration行
( ってた is the spoken contraction of 行( っていた, “had gone”.見
( 抜( く means to see through something and discern the truth; 〜てしまったんだ presents the deduction as already completed and a bit impressive.
