Bab 274: Difference between novice and expert

" The maid killed herself?" Yu Lingyun asked with a frown as he looked at Zhai Heng who solemnly nodded, they have been looking for the killer who assassinated Consort Liu and Consort Su, after much looking around they finally caught a clue and were so looking forward to dealing with this case once and for all but then the clue was killed as well! 

Zhai Heng had asked one of his shadow guards to keep an eye on the maids of the kitchen, in fact, he did not think that he will find any clues after so long but surprisingly his shadow guard brought him the information that one of the maids from the kitchen was actually acting suspicious, she was responsible for filling up the barrels but these days she was refusing to do so and she even stopped washing the barrels.
