Sometimes spelling inaccuracies, grammar, false information gets so bad in this genre in the book department. As I stated in another thread which reminded me of this annoying facet, I own roughly 50-60 organized crime books (around 50 hard copies and 10-12 kindle). I think all but one or two have obvious and embarassing spelling errors. Sometimes incorrect spelling and grammar are combined with false information making you want to throw the book down.

Examples:

Lion in the Basement (horrible book anyways, horrible plot, too many errors to count)

Any book by Philip Carlo

Castellano is spelled "Castalano" in "The Company She Keeps" by Georgia Durante

The list goes on and on...Post any books and the inaccuracies they have in this thread
