"Well, I will explain," replied Mr. Brown. "Here are the facts, by your own showing. On a warm evening in spring, and in calm weather, John Darche fell overboard. I do not say he threw himself overboard, though it was said that he did, to get away from the detective, possibly it may have been an accident after all. We do not know. He was seen to go over by some one, possibly by two ladies. It was very likely at supper-time. We do not know that either. But it is quite sure that there were not many people about. The ladies screamed, as was natural, called for help and all that sort of thing. But on a calm May night those channel boats run very fast. They did not cry out 'man overboard!' as a sailor would have done, and very probably five minutes elapsed before the Captain gave the order to stop. In that time the boat would have run a mile and a half. It could not stop inside of half a mile. Well, do you know anything about the tides and currents in the Channel? The steamer could not have gone back to the point at which Darche was lost much inside of twenty minutes. In that time the current may have carried him a mile or more in one direction or the other. Every one remembers that Darche was a good swimmer. As it happened in May, he was not burdened with an overcoat, or thick boots, and there are always vessels about in the Channel. Why is it so very improbable that he should have been picked up by one, outward bound--" While he was speaking, Brett played nervously with an unlighted cigar, which he held in his hand. "A sailing-vessel outward bound from England to South America would not be in the Channel," observed Vanbrugh. "Nobody said she was from England," retorted Brown. "She may have been from Amsterdam. A great many Italian vessels take in cargo there." "Surely she would have stopped and put Darche ashore," said Greene with conviction. But the others laughed. "You are not much of a sailor," said Brown. "You cannot stop a sailing-vessel, as you express it, and run into any harbour you like as though she were a steam-tug. To put back might mean a loss of two or three weeks to the captain. Upon my soul, Vanbrugh, I cannot see why it is so improbable." "You are not in earnest, Brown?" asked Brett anxiously. "I am, though. A case like that happened not very long ago. Everybody knows about it. It is a fact. A man came back and found his wife married to somebody else." "Enoch Arden!" suggested Greene contemptuously. "Precisely the same thing. The man had been living somewhere near San Francisco. After he came back he found his wife had married an old friend of his--a very good fellow. He would not break her heart, so he went off to live by himself in the Rockies." "I wish you would stop!" exclaimed Brett, almost livid. "I wonder it does not strike you in the same way," continued Mr. Brown, unmoved. "You are a lawyer, Vanbrugh. Now just argue the case, and meet my points."
