A mathematician and author, Luke Williams, is travelling up to London on a train when he meets a old lady, Lavinia Fullerton, who is also going to London, to Scotland Yard. Lavinia tells Luke that in her small village several people have died. The local police are certain that it was all accidental and are taking no action but Lavinia isn't convinced. In London Luke watches, horrified, as Lavinia is run over in a hit and run and he becomes convinced that she was telling the truth. He travels down to the village and with the aid of a local girl, who is also convinced that the deaths were murder, sets out to solve the mystery.
如何评价《杀人不难》
首先声明，我是真的挺喜欢这部《杀人不难》小片的，n刷过后我也看了一些导演和演员的相关采访，对这个电影也有了一些更深的感受和想说的话。这其实是于适自己在路演的时候对电影的形容，我觉得还挺准确的：他说这部电影就像一瓶冰镇过的橘子姜味汽水，一开始喝下去凉爽愉悦，但最后回味起来又会有点辛辣苦涩，我现在可以说就处在这个回味的阶段。
优酷网友热评：慕名去看，画面很精致，演技也在线，台词意味深长，编剧非常用力，最终呈现出来的是一支华丽的舞蹈。
来自网易云网友的评价：导演以自身的传统美学功底，对电影的写实艺术特性也有精深的理解和把握，他特别擅以生动的细节描绘人物的内心活动，并调动电影的各种艺术元素为塑造人物服务。
