Marie: "Je suis bouleversée, Hunter. Ce que j'ai vu ce soir m'a glacé le sang." Hunter: "I don't understand French. What happened? Tell me in English." Marie: "Je ne parle pas anglais." Hunter: "Then describe it in French, and I'll piece it together as best I can." Marie: "D'accord. Des ombres près du café, une silhouette qui disparaît dans une ruelle." Hunter: "Shadows by the cafe, a silhouette vanishing into a back alley. What happened after that?" Marie: "Il y avait un cri étouffé et un bruit métallique, comme une boîte qui tombe, puis le silence." Hunter: "A muffled scream and a metallic clang, then silence. Where did this take place exactly?" Marie: "Autour du quai et du café du coin; je suis restée là, appareil photo en main." Hunter: "The Apple Festival rumors are spreading. Let me see your photos later." Marie: "Oui. Mes photos ne mentent pas; regardez-les et vous verrez ce que les mots ne disent pas." Hunter: "I’ll look at them later. I’ve got a call I need to take." Hunter: "I’ve got to go. I’ll be back as soon as I can." Marie: "D’accord. Je vous attends ici, avec mon appareil."
