第六十九章(6/9)

                                                                 凶手可能就在看过照片的人当中。
                                                                                                                                                                假定有一个朋友或熟人是六个受害者共同的朋友或熟人，那么这个人可能看了六人的照片，从而蜕变为星期五的汉子。
                                                                                                                                                                议论一下之后，龟井问十津川：“要不要查一查？”
                                                                                                                                                                “查一下。”十津川说，“不过，获救的永久纪子作证说完全不认得凶手。从背后袭击，没看到脸，只听见声音，我想，若是让人看自己的泳装照片，那声音也一定听得出。”
                                                                                                                                                                                                                                                                                                                           “也许是男方的朋友。受害人的情人或朋友拿她们的照片给别人看。如果对照片很反感的人是凶手，受害人不认识对方，也是正常的的。”
                                                                                                                                                                “这说法也对，尤其不受女方欢迎的男子更会起反感。那就先调查一下六个受害人的情人或朋友周围的人看过泳装照片的男子。”十津川这样决定说。
                                                                                                                                                                可是，尽管龟井等刑警费了九牛二虎之力，这项调查的结果也只是失望。
                                                                                                                                                                六个受害人之间没有任何关系，她们的情人或朋友间也没有横向联系。
                                                                                                                                                                所以，看过泳装照片的人都互无关系，又没有一个人看过全部泳装照片。
