第七节(1/4)

联合专案小组组成的第一天，由十津川先召集五人，举行了侦查会议。
                                                                                                                                                                “先确认这两件命案的共同点好吗？”十津川面对黑板说。这样似乎可以让凶犯的形象浮现出来。
                                                                                                                                                                “第一是凶犯的血型。”安井说。
                                                                                                                                                                “凶犯血型B。”
                                                                                                                                                                十津川在黑板上写下这几个字。
                                                                                                                                                                “这也许是偶然的，两件命案都发生在星期五。”池袋警察局的白石说。
                                                                                                                                                                “这点我也注意到了。”十津川说：“我们就把这次的凶犯称为‘星期五的汉子’好了。也许星期五含有什么意义。此外，还有什么吗？”
                                                                                                                                                                “还有，”安井说，“这两起命案凶犯都把被害人的衣服扒光。最近发生的另一起强奸杀人案，凶犯只裸裎下半身，与这两起完全不同。田岛兄说，这是凶犯有抢劫的动机，我不认为是这样。”
                                                                                                                                                                “你认为这点显露了凶犯的性格？”十津川颇感兴趣地问安井。
                                                                                                                                                                “虽然不一定这么说，但也值得注意。第一件命案，也许如田岛所说，杀人后想抢劫才摘下手表，但因是女表怕被追查又扔掉了。可是，第二件命案也摘下了手表，而且也照样扔掉了，似乎没有杀人抢物的意思。我想，凶犯的罪恶动机是让女的完全彻底的赤裸。”安井又谈出了自己的看法。
