"Three times in the course of my journey from London to Winchester I have taken Margaret's strange letter from my pocket-book, and have read the familiar lines, with the idea of putting entire confidence in my companion, and placing the letter in his hands. But in order to do this I must tell him the story of my love and my disappointment; and I cannot bring myself to do that.

"'We can't do better than put up at the hotel where the suspected party was stopping at the time of the event we're looking up,' Mr. Carter said to me, as we strolled away from the station, after giving our small amount of luggage into the care of a porter; 'we shall pick up all manner of information in a promiscuous way, if we're staying in the house; little bits that will seem nothing at all till you put them all together, and begin at the beginning, and read them off the right way. Now, Mr. Austin, there's a few words I must say before we begin business; for you're an amateur at this kind of work, and it's just possible that, with the best intentions, you may go and spoil my game. Now, I've undertaken this affair, and I want to go through with it conscientiously; under which circumstances I'm obliged to be candid. Are you willing to act under orders?' "I told Mr. Carter that I was perfectly willing to obey his orders in everything, so long as what I did helped the purposes of our journey.
