I was hesitant to look for the maniac.

"As my friend says: 'To be or not to be'"

Let's consider it from a different perspective: 'To be or not to be' is Hamlet's monologue. Hamlet's friend is Horatio.

and a head from the Quran was pinned to the door with a knife.

The only thing I found about this is the actor Peter Falk, who has Horatio as his avatar and played one of the roles named "Horatio" and participated in the film "The Prophet" (a connection to the Quran). But somehow, this seems doubtful to me + the pianist's music would have blocked the person + the ND cheater...
