Chambers's Journal of Popular Literature, Science, and Art, No. 729, December 15, 1877

I am a professional man, and reside in the West End of London. One morning some few months back, my assistant on coming to attend to his duties produced a bunch of keys, which he informed me he had just picked up at the corner of a street leading from Oxford Street.
'Hadn't they best be handed over to the police?' suggested my assistant. I wish to goodness I had at once closed with his suggestion; but I didn't, much to my own cost, as will be presently seen.
'Well, I don't know,' was my answer. 'I rather think it will be a wiser plan to advertise them, if the owner is really to have a chance of recovering them; for to my mind, articles found in that way and handed over to the police are rarely heard of again.'
An advertisement for the Times was duly drawn up and sent off for insertion. It merely stated where the keys had been picked up, and where the owner of the bunch could have it returned to him on giving a proper description. The next morning the advertisement appeared; and though I half expected that some applications might be made later on in the same day, it passed over quite quietly. But the following morning I had a foretaste of the trouble that awaited me so soon as the postman had deposited my letters in the box and given his accustomed knock. A glance at my table shewed me that my correspondence was very considerably beyond its average that morning. The very first letter I opened was in reference to the advertisement; and before I had gone through the collection I found there were over twenty applications for the bunch of keys in my possession. Some of the writers took the trouble to describe the keys they had lost; but none of them were in the least like those that had been picked up by my assistant. Some did not take the trouble to give any description at all, or to state if they had been in the part of the town where the keys were found; and a few boldly claimed them on the strength of having dropped a bunch miles from the spot indicated in the advertisement!
