Edna Buchanan has won the Pulitzer Prize for her crime reporter, and she has a popular following for her Britt Montero mystery series. Britt is a Miami crime reporter and she is not pleased when Hollywood movie star Lance Westfell arrives to shadow her in preparation for his new movie. Britt doesn’t want to babysit a movie star, but her boss demands it. Lance is being stalked by an obsessed fan, and soon violent things start to happen. Also, Britt falls for Lance so a little romance sweetens the story. Margin For Error was not my usual cup of tea, but I might read some of the other Britt Montero mysteries as I did like the character.
