Library Murder Case

Situation
A routine afternoon at the library turns into the hunt for a corpse after an attendant turns up missing. When Conan and the Detective Boys try to solve the mystery by staying after-hours, they find themselves trapped, in the dark, and not alone. Will they catch the killer before he catches them?

Resolution
Hide= Shuji Tsugawa is the culprit and he hid the corpse above the elevator. Tamada discovered the illegal drugs hidden inside the fake books which means Tsugawa is a drug dealer and that's why Tsugawa killed him to keep him quiet.

After finishing the case, Conan walked back with the Detective Boys, thinking that should be his final case in Conan's form, as he will be drinking Paikaru afterward and turning back to Shinichi Kudo permanently. However, a second round of Paikaru didn't work for him, and the next day Conan appeared to be hung over in front of the Detective Boys.
