Xiao Liulang was escorted away by an errand boy from Huichun Hall before he had a chance to step foot in the bookstore. He went straight to Huichun Hall to procure medicine, and everyone at the hall could serve as witnesses to his whereabouts, so naturally no one suspected him.
Gu Dashun, however, was a different story. Someone had seen him on the second floor, right where the victim's room was located.
The victim had happened to be away at that time, and Gu Dashun was the only one on the second floor.
Those who have visited the bookstore knew that the second floor, aside from office rooms, contained guest rooms reserved for the elite and were not open to ordinary folks. In theory, a poor scholar like Gu Dashun should not have been on the second floor at all.
Gu Dashun cried out in innocence, "An old man asked me to fetch some books for him upstairs! He said he wanted to discuss poetry and philosophy with me!"
