As thick as thieves

Where does the phrase "Thick as thieves come from"?

PS. I am keeping the word "Pease" alive - its my last name!

"The pudding is itself now becoming less common as it has been largely superseded by 'mushy peas', which is essentially the same thing. Once that process is complete, 'pease' will be gone from the everyday language - a pity."
