Thompson." "Yes, I have." "You didn't happen to remark what the post-mark was, perhaps?" "No," says he, "I didn't." "Come," says I, "I'll be plain with you. I'm in a small way of business, and I have given Thompson credit, and I can't afford to lose what he owes me. I know he's got money, and I know he's in the country, and if you could tell me what the post-mark was, I should be very much obliged to you, and you'd do a service to a tradesman in a small way of business that can't afford a loss." "Well," he said, "I do assure you that I did not observe what the post-mark was; all I know is, that there was money in the letter - I should say a sovereign." This was enough for me, because of course I knew that Thompson having sent his wife money, it was probable she'd write to Thompson, by return of post, to acknowledge the receipt. So I said "Thankee" to the postman, and I kept on the watch. In the afternoon I saw the little girl come out. Of course I followed her. She went into a stationer's shop, and I needn't say to you that I looked in at the window. She bought some writing-paper and envelopes, and a pen. I think to myself, "That'll do!" - watch her home again - and don't go away, you may be sure, knowing that Mrs.
Thompson was writing her letter to Tally-ho, and that the letter would be posted presently. In about an hour or so, out came the little girl again, with the letter in her hand. I went up, and said something to the child, whatever it might have been; but I couldn't see the direction of the letter, because she held it with the seal upwards. However, I observed that on the back of the letter there was what we call a kiss - a drop of wax by the side of the seal - and again, you understand, that was enough for me. I saw her post the letter, waited till she was gone, then went into the shop, and asked to see the Master. When he came out, I told him, "Now, I'm an Officer in the Detective Force; there's a letter with a kiss been posted here just now, for a man that I'm in search of; and what I have to ask of you, is, that you will let me look at the direction of that letter." He was very civil - took a lot of letters from the box in the window - shook 'em out on the counter with the faces downwards - and there among 'em was the identical letter with the kiss. It was directed, Mr. Thomas Pigeon, Post Office, B-, to be left till called for. Down I went to B- (a hundred and twenty miles or so) that night. Early next morning I went to the Post Office; saw the gentleman in charge of that department; told him who I was; and that my object was to see, and track, the party that should come for the letter for Mr. Thomas Pigeon. He was very polite, and said, "You shall have every assistance we can give you; you can wait inside the office; and we'll take care to let you know when anybody comes for the letter."
Well, I waited there three days, and began to think that nobody ever WOULD come. At last the clerk whispered to me, "Here!
Detective! Somebody's come for the letter!" "Keep him a minute," said I, and I ran round to the outside of the office. There I saw a young chap with the appearance of an Ostler, holding a horse by the bridle - stretching the bridle across the pavement, while he waited at the Post Office Window for the letter. I began to pat the horse, and that; and I said to the boy, "Why, this is Mr. Jones's Mare!" "No. It an't." "No?" said I. "She's very like Mr. Jones's Mare!" "She an't Mr. Jones's Mare, anyhow," says he.
"It's Mr. So and So's, of the Warwick Arms." And up he jumped, and off he went - letter and all. I got a cab, followed on the box, and was so quick after him that I came into the stable-yard of the Warwick Arms, by one gate, just as he came in by another. I went into the bar, where there was a young woman serving, and called for a glass of brandy-and-water. He came in directly, and handed her the letter. She casually looked at it, without saying anything, and stuck it up behind the glass over the chimney-piece. What was to be done next?
'I turned it over in my mind while I drank my brandy-and-water (looking pretty sharp at the letter the while), but I couldn't see my way out of it at all. I tried to get lodgings in the house, but there had been a horse-fair, or something of that sort, and it was full. I was obliged to put up somewhere else, but I came backwards and forwards to the bar for a couple of days, and there was the letter always behind the glass. At last I thought I'd write a letter to Mr. Pigeon myself, and see what that would do. So I wrote one, and posted it, but I purposely addressed it, Mr. John Pigeon, instead of Mr. Thomas Pigeon, to see what THAT would do.
In the morning (a very wet morning it was) I watched the postman down the street, and cut into the bar, just before he reached the Warwick Arms. In he came presently with my letter. "Is there a Mr. John Pigeon staying here?" "No! - stop a bit though," says the barmaid; and she took down the letter behind the glass. "No," says she, "it's Thomas, and HE is not staying here. Would you do me a favour, and post this for me, as it is so wet?" The postman said Yes; she folded it in another envelope, directed it, and gave it him. He put it in his hat, and away he went.
'I had no difficulty in finding out the direction of that letter.
It was addressed Mr. Thomas Pigeon, Post Office, R-, Northamptonshire, to be left till called for. Off I started directly for R-; I said the same at the Post Office there, as I had said at B-; and again I waited three days before anybody came. At last another chap on horseback came. "Any letters for Mr. Thomas Pigeon?" "Where do you come from?" "New Inn, near R-." He got the letter, and away HE went at a canter.
