I turned it over in my mind.
“Yes,” I said, “it is morally justifiable so long as our object is to take no articles save those which are used for an illegal purpose.”
“Exactly. Since it is morally justifiable, I have only to consider the question of personal risk. Surely a gentleman should not lay much stress upon this, when a lady is in most desperate need of his help?”
“You will be in such a false position.”
“Well, that is part of the risk. There is no other possible way of regaining these letters. The unfortunate lady has not the money, and there are none of her people in whom she could confide. To-morrow is the last day of grace, and unless we can get the letters to-night, this villain will be as good as his word and will bring about her ruin. I must, therefore, abandon my client to her fate or I must play this last card. Between ourselves, Watson, it's a sporting duel between this fellow Milverton and me. He had, as you saw, the best of the first exchanges, but my self-respect and my reputation are concerned to fight it to a finish.”
“Well, I don't like it, but I suppose it must be,” said I. “When do we start?”
“You are not coming.”
“Then you are not going,” said I. “I give you my word of honour—and I never broke it in my life—that I will take a cab straight to the police-station and give you away, unless you let me share this adventure with you.”
“You can't help me.”
“How do you know that? You can't tell what may happen. Anyway, my resolution is taken. Other people beside you have self-respect, and even reputations.”
