: Where does this come from? It is the title of a school book my 9 year old son is reading at the moment. One of the questions at the back is about how the title relates to telling the truth. I have told him that "come clean" means tell the truth, but can't tell him how the saying came about. Any ideas?

to make a clean breast of it -- mid to late 18th century. To confess, to own up unreservedly. Come clean, 19th century, the same as "to get it off your chest." From "Cassell's Dictionary of Slang" by Jonathon Green (Wellington House, London, 1998). Page 763.

My theory. Most people, when they have told a lie or done something wrong, will feel "heavy hearted." The emotional stress makes their chest hurt. Telling the truth -- or getting it off their chest -- relieves the pressure. Of course, sometimes telling the truth gets the person in trouble. That's the downside.
