Testfor a written book in 1.8 with custom name and writing

So I’m working on a map and need help with the Testfor command. I’ve looked around and tried out several different things and just messed around with the command without help, but I can’t get it to activate with the book in hand. Here’s the command I have set up, but it doesn’t work.

/testfor @a {SelectedItemSlot:8,Inventory:[{Slot:8b,id:minecraft:written_book,tag:{pages:["["",{"text":"Master, I have done as you told me, Minera will soon fall to your Undead Army. I still have not figured out how to obtain the sword, but you were right to check the bookshelf before attempting more drastic measures... (the note is torn)"}]"],display:{Name:"Torn Note"}}}]}

Now here’s a different version, but without a book (this one works perfectly).

/testfor @a {SelectedItemSlot:8,Inventory:[{Slot:8b,tag:{display:{Name:"Torn Note"}}}]}

My problem is that with a book the second command doesn’t light up and I really want to use a book for this part of my map.

Also I should say, the command for the book itself should be fine, I used a JSON Minecraft generator and it works fine with /give. I did edit the format slightly to try to get the testfor command to work, but it didn’t.
