How it was that I, being so young a man and not a very tactful one, was sent on such an errand is more than I should be able to explain. But many years ago some one came to me with a request that I should go that evening to a certain street at King's Cross, where would be found a poor lady in great distress; that I should take a small sum of money which was given to me for the purpose in a little packet which disguised all appearance of coin, present it to her as a parcel which I had been desired to deliver, and ask if there were any particular service that could be done for her.
