L'Ami commun
"Our Mutual Friend", like most Dickens novels, was published in monthly instalments. Each of the 19 instalments cost one shilling (with the exception of the nineteenth, which was double-length and cost two). Each issue featured 32 pages of text and two illustrations by Marcus Stone. Sales of "Our Mutual Friend" were 35,000 for the first monthly number, but then dropped by 5,000 for the second number. The concluding double number (instalments XIX-XX) sold 19,000.
