While Thomas Killingbeck, a compositor, and Peter Bishop, a proofreader, were working for Richardson in his print shop during 1753, Richardson discovered that printers in Dublin had copies of "The History of Sir Charles Grandison" and began printing the novel before the English edition was to be published. Richardson suspected that they were involved with the unauthorized distribution of the novel and promptly fired them. Immediately following the firing, Richardson wrote to Lady Bradshaigh, 19 October 1753: "the Want of the same Ornaments, or Initial Letters in each Vol. will help to discover them [if exported into England, although they should put the Booksellers Names that I have affixed. I have got some Friends to write down to Scotland, to endeavour to seize their Edition, if offered to be imported". There were four Dublin presses used to make unauthorized copies the novel, but none of them were able to add the ornaments that could effectively mimic Richardson's own. However, there were still worries about the unlicensed copies, and Richardson relied on seven additional printers to speed up the production of "Grandison".
