Read it through once

Next I found the bank, and asked for some money, but I had left my letter of credit somewhere and was not able to draw. I remembered now that I must have left it lying on the table where I wrote my telegram; so I got a cab and drove to the Post Office and went upstairs, and they said that a letter of credit had indeed been left on the table, but that it was now in the hands of the police authorities, and it would be necessary for me to go there and prove property. They sent a boy with me, and we went out the back way and walked a couple of miles and found the place; and then I remembered about my cabs, and asked the boy to send them to me when he got back to the Post Office. It was nightfall now, and the Mayor had gone to dinner. I thought I would go to dinner myself, but the officer on duty thought differently, and I stayed. The Mayor dropped in at half past ten, but said it was too late to do anything to-night—come at 9.30 in the morning. The officer wanted to keep me all night, and said I was a suspicious-looking person, and probably did not own the letter of credit, and didn’t know what a letter of credit was, but merely saw the real owner leave it lying on the table, and wanted to get it because I was probably a person that would want anything he could get, whether it was valuable or not. But the Mayor said he saw nothing suspicious about me, and that I seemed a harmless person, and nothing the matter with me but a wandering mind, and not much of that. So I thanked him and he set me free, and I went home in my three cabs.
