I had never defrauded a man of a farthing, nor called him knave behind his back. But now the last rag that covered my nakedness had been torn from me. I was branded a blackleg, card-sharper, and murderer.

God's bones! Whenever I go to beat those knaves / my tapsters, out she my wife comes with clubs and staves, / "Go on!" she screams — and it's a caterwaul — / "You kill those dogs! Break back and bones and all!"
