可以用：detective novel
引用薩繆爾·貝克特的作品介紹：
Molloy,for instance,still retains many of the characteristics of a conventional novel—time,place,movement and plot—and is indeed,on one level,a detective novel.
也可以用：detective story
引用英文網(wǎng)站detective-story：
The detective story soon expanded to novel length.
我個人認(rèn)為用第一個比較好.
