The Scar

I take it you’ve seen the scar on Captain Blood’s neck.
He claims he got it from a duel.
In a way, I suppose that’s the truth, but it wasn’t a fair duel.
His strategy is to draw his sword, then pull a pistol and shoot his opponent in the chest.
Once, he had a misfire, and was forced to reach for his other pistol.
That gun fired true and killed his opponent.
So how was he cut?
He slashed his own neck, reaching for the other pistol.
Don’t tell him that, though.
Or he’ll challenge you to a duel.
