As he slept upstairs on September 8th of 1908, two young burglars entered Mark Twain's home, took an entire sideboard into the garden and proceeded to break it open. They were eventually caught by police with a stash of silverware. The next day, with the help of an aspiring young artist named Dorothy Sturgis, Twain produced the following note for the attention of future burglars. From that day on, it was permanently attached to his front door.

To the next Burglar.
There is nothing but plated ware in this house, now and henceforth. You will find it in that brass thing in the dining-room over in the corner by the basket of kittens. If you want the basket, put the kittens in the brass thing. Do not make a noise — it disturbs the family. You will find rubbers in the front hall, by that thing which has the umbrellas in it, chiffonier, I think they call it, or pergola, or something like that.
Please close the door when you go away!
Very truly yours,
