Maddie knows full well that Julie will probably believe she’s dead when Julie sees the photos. She knows the photos will hurt her friend, but she also knows Julie has to get the photos at some point if Maddie expects to get out of the country alive. And because Maddie knows how clever Julie is, she realizes that the photo of the 11 wireless sets will buy Julie time. Indeed, recall that Julie bought her clothes back with “code” for those wireless sets. Maddie is, again, able to help Julie because of how well the women know each other.
