The marketing team at St. Martin's Press is hoping the media isn't opposed to judging a book, or at least a galley, by its cover. The publisher has been making a concerted effort to do more inventive galley mailings, putting some of its mystery titles in everything from clear, police-style evidence bags to bloodstained interoffice envelopes. Though St. Martin's isn't the only house taking this tack, senior director of creative services Nancy Trypuc said the frequency of the mailings reflects an effort to draw more attention to the house's Minotaur imprint. “We're really saying, 'Hey, notice us,' ” Trypuc explained, adding that the approach won't work for every book, but is ideal for those with “a hook.”
