顾淮看着他那副后知后觉的模样，有些好笑地摇了摇头，端起茶杯抿了一口。
“二哥，你这反应，倒也不算太慢。”
赵知武重新坐回石凳上，但脸上的兴奋很快就退了下去，取而代之的是一抹深深的忧虑。
“可是，妹夫，这终究只是你的推测。”
“刺杀公主是何等大事，昨夜的事情已经传遍了整个洛安城，那些高官显贵人人自危。”
“陛下在朝堂上更是顶着极大的压力，下旨命令我，必须给全天下人一个交代。”
他苦着脸，双手一摊，显得十分无奈。
“没有真凭实据，我总不能直接去跟陛下说，这是草原人的阴谋吧。”
“那些御史言官的唾沫星子，当场就能把我给淹死。”
顾淮放下茶杯，身子微微前倾，清亮的眸子里闪过一丝高深莫测的光芒。
“证据，其实早就留下来了，只是你们这些查案的人，眼睛都长在头顶上，瞧不见罢了。”
赵知武眼睛一亮，急忙凑了过来。
“什么证据，你快说。”
顾淮伸出右手食指，在冰凉的石桌上轻轻敲了敲。
“我问你，那些刺客潜伏在麓山，手里拿着的是什么兵刃。”
赵知武挠了挠头，仔细回想了一下。
“听禁军的校尉说，现场留下的除了极像党项工艺的战刀，倒也没发现别的特别之物。”
顾淮冷笑了一声，身体往后一靠。
“战刀易得，大楚的黑市上，只要肯花银子，什么兵刃买不到。”
“但有一样东西，他们绝不可能大摇大摆地带进关内。”
他看着赵知武，一字一顿地吐出两个字。
“弩箭。”
“而且是军中禁用的精钢短弩。”
赵知武的瞳孔骤然收缩，脸色瞬间变了。
大楚对强弩的管控，严苛到了极点，非军中精锐不得配用。
私藏强弩者，在大楚律例中，几乎等同于谋反。
“大楚沿途的关隘防守严密，特别是对待异族商旅，盘查之严，连一片铁甲都带不进来。”
“党项国和靺鞨部族前来洛安的消息，传回朝廷才过去多久。”
“草原王庭就算反应再快，也绝不可能在这么短的时间内，带着大批军用强弩，绕过关隘，神不知鬼不觉地潜入洛安城。”
顾淮的声音很轻，却带着一种不容置疑的笃定。
“所以，只有一个解释。”
赵知武咽了一口唾沫，只觉得嗓子有些发干。
“什么解释。”
“在洛安城里，有草原人的内应，而且这个内应的身份极其不简单，能在大楚的眼皮子底下，为他们提供这些禁用的弩箭。”
顾淮看着赵知武。
赵知武只觉得一股凉意从脚底板直冲天灵盖。
“洛安城里……有草原人的卧底。”请求出错，状态码:502内容:<!DOCTYPE html>
