WHAT WAS THE RED MARK ON MONKS NECK FROM

I'm not sure this is told to us. He is physically unattractive, has a dark red mark on the left side of his jaw, is subject to severe epileptic fits, and completely cowardly, not willing to outwardly be associated with any form of crime (this is not because he is a moral being, but because he fears being caught). Dickens keeps his motives and his true identity a total secret until nearly the end of the novel, thus surprising the reader with an unexpected revelation that adds complications to the plot.

okay ;-) I actually checked this to see if you found the answer.... mine was the same, but I thought there had to have neen something more exact, and I didn't have the text.
