The book's accuracy is hard to establish, since it went through a number of revisions, not all with Grimaldi's input. Grimaldi's original manuscript, which he mostly dictated, was about 400 pages long; he completed it in December 1836. The original "excessively voluminous" version was apparently not good enough for publication, and in early 1837 he signed a contract with a collaborator, the obscure Grub Street writer Thomas Egerton Wilks.
