9月10日星期六鲁库夫家的耕牛丢了,鲁库夫硬说是他的邻居兼同班同学7岁的拉文斯基把牛放走的。两人吵着来到了科勒探长的办公室。鲁库夫说:“探长,拉文斯基用他爸爸的裁缝剪刀剪断了拴牛的缰绳,把牛放走了。”拉文斯基带着哭腔委屈地说:“探长,我连鲁库夫家的牛拴在哪里都不知道。” Ruukhov's cattle were lost on Saturday, September 10, and Ruukhov bluntly said that his neighbor and classmate, Ravinski, 7, had let the cattle go. The two clamored to come to Detective Kohler's office. Ruukhov said: “Inspector, Ravinsky with his dad's tailor scissors cut off the bridle bridle, the cow let go. ” Ravinski said with a grievance: “Inspector, I do not even know where the cowhide in Ruukhov was tied. ”
