Locations for shooting

I still need inside areas to shoot where people will be murdered but i have all outside locations ready for shooting and im going to ask 2 libraries whether i can film inside and have cast behind the counter. I will call the library in Sprowston first and then the the library inside The Forum at Norwich too.

 The three pictures above are possible locations for when a member of the public stumble upon the book covered in blood.

like these current frames featured in my storyboard.
