皮影戏

12、自杀？他杀？

谭可菲和孟凡刚赶到老李家，里面就传出震动天地的哭喊声。进了老李房间，他们看到老李尸体的蜷缩在床上，嘴角有血流出来。

张煜迎了上来说道：“目前显示死者是咬舌自杀的。”

谭可菲：“没有其他的而发现吗？”

“我们查看了尸体，根据尸体的硬化程度和肢体扭曲程度说明死者死前痉挛过，死亡时间大约是昨晚凌晨一点左右。但是按理说咬舌自尽的身体应该不会有痉挛现象的。”

“你的意思是？”

“死者应该是不想自杀的，但全身抽搐会导致人不受控制地咬住自己的舌头。所以这是一场谋杀。而且在现场发现了这个。”张煜举起一个透明塑料袋里面有一个环状物体，环上还带着一个细细的柄，“这是消防栓。我想凶手是用干冰灭火器杀人的。当人周围气体中有超过20%的二氧化碳，那么人体吸入后会剧烈痉挛，几秒钟就会咬舌而死且身体冰凉。而干冰会升华为二氧化碳，由于二氧化碳的密度比空气大因此会沉在特定空间的下面。我刚才用点燃的火柴在尸体周围试过，虽然没有立即熄灭但火焰明显便小了。现在只要找到那个灭火器就有了足够的物证。”

谭可菲听到这里立即把张煜和孟凡拉出了门外着急的说：“昨晚你们不是守着吗？叶老师傅不可能是凶手，那老李到底是谁杀死的？”

张煜：“不！凶手一定是叶老师傅。我们昨晚上楼时叶老师傅确实在睡觉，但这并不保证之前他没从另一个楼梯出去过。”

谭可菲脑子懵了，忽然她像是记起了什么赶紧跑到叶老师傅的家，毫不犹豫的上了二楼，快步走到走廊尽头，看到了另一个楼梯，忽然她觉得一阵晕眩扶住了墙不敢相信的看着那个楼梯。

楼梯上是凌乱的脚印，但第一次看到的时只有一串脚印。这说明了一切。叶老师傅昨晚下去过，他到老李家杀了老李！

13、大结局

“小姑娘，你很聪明。”叶老师傅的声音在谭可菲毫无准备的情况下传了过来。她转过身去，身后正站着叶老师傅，手里还拿着一个没了消防栓的灭火器。她震惊地盯着那个灭火器。

“你为什么要这么做？”谭可菲。

“为什么？因为他们当年杀死了我的妻子还有她肚子里的孩子！我的孩子都七个月了啊！你说！他们该不该死？！”叶老师傅情绪已经完全失控，像疯了一般地怒吼。

“不！你现在杀了最无辜的两个人！”

“胡说！他们无辜，我的妻儿就不无辜吗？！”叶老师傅听言更加愤怒一步步向谭可菲逼近。

谭可菲一边向后移动一边想办法稳住他，“当年您妻子死前不是留下一个‘3’字吗？杀害您妻子的就只有一个人，您不是说过您的妻子是永登红城镇人吗？您也是皮影界的老将了，应该知道江湖隐语吧？”

叶老师傅像是没有听到般继续向谭可菲靠近。

“在兰州皮影隐语里‘3’字对应的是‘王’字。”

叶老师傅止住了脚步，突然像是失去支撑的木偶瘫坐到地上，手松了灭火器滚到了谭可菲脚前。她往后看了看是黑洞洞的楼梯，自己只要再往后挪一小步就会摔下楼去。

尾声

那天，叶老师傅对着他妻子的遗像演完了他人生最后一场戏《鹊桥渡》，然后被警察带走了。三人收拾好行李准备回上海，走到大厅时看到桌上放着三包金银花干，他们看了看各自拿了一包放进包里。

深夜，谭可菲在家中静坐着。她终于明白了为什么叶老师傅家的门会不关，他是怕妻子回不了家。她看着杯中一朵朵盛开的金银花，恍若隔世。桌边放着一张照片，照片上，手拿两个精致皮影人的老人在金色的阳光下笑容如春风般和煦。
