A police officer who takes to crime is likely to be more successful at it than most. The gamekeeper turned poacher has everything going for him.

一个警官去犯罪要比大更容易得手，就像猎场看守去偷猎，真是再容易不过的事。

Since his days as a militant student, he has cut his hair, put on a suit and is now the classic example of the poacher turned gamekeeper.

自从成为军校学生之后，他剪了头发，穿上套装，成了浪子回头金不换的典型。
