This would be fine if it were one or two chapters for this mystery, but this is also not good mystery writing. You want to give enough information to the audience for them to solve it, and then include things like red herrings to trip up the reader. The longer this runs, the more that becomes an issue.
EDIT: Also, I know Meiling is supposed to be pouring tea behind her head, but it looks like it is going straight through her head.
