For this next quest, Jauffre sends you back to the Imperial City to check up on Baurus, the bodyguard who helped you at the start of the game.
Fast travel to the elven gardens district, and go to Luthers Boarding house where he has his current residence. Inside you'll find him seated at the bar.
Rather then a warm welcome, he'll instruct you not to say anything but to simply sit down next to him, do so and he'll mention someone sitting behind the two of you might be a spy.
As instructed, wait till Baurus get's up, then see the other person following him and follow the other person. A short fight follows, make sure Baurus survives. Speak to him to learn the attacker is part of the Mythic dawn cult.
Baurus suggests you investigate further on the book you find on the attacker's body, and suggests you speak to Tar-Meena at the arcane university. She's usually found there in the lobby of the arch-mage's tower.
Speak to her about the book and she'll mention you need all 4 books to figure out the next clue, she gives you the second part and instructs you to go to the first edition bookstore in the Market district to find the third part.
Once you speak to the shopkeeper there you'll find he does indeed have the book, but is holding it for someone. You have several options here, the first is getting the disposition of the shopkeeper over 70 and he'll sell you the book rather then wait for the other customer, I don't recommend this as you need the other guy (Gwinas) anyway.
Second is either pickpocking Gwinas for both the book and a note on a meeting he's arranged to get the fourth book, and killing him for that same information is also an option btw.
There's also a peacefull solution though, Follow Gwinas back to his room at the Tiber Septim hotel, confront him with the knowledge that you know he has that book and tell him the mythic dawn was behind the murder on the emperor and he'll hand over both the book and the info without a fight.
Once you have both, speak to Baurus once again, standing outside of the boarding house this time, and he'll ask you to follow him to that meeting right now. Be prepared as you'll face three mythic dawn assassins.
Follow baurus into the sewers, and fight your way past another few rats and mudcrabs and such and you'll reach the place just outside the room where the meeting is scheduled, here Baurus asks you if you want to be the one to go in, or if you wish to be the backup, choose and either go in through the door, or up the stairs. Either way, the cultists come in, speak for a bit and then attack.
Kill them and on the body of Raven Camoran you find the fourth and last book of the series. Baurus will mention taking off for cloud ruler temple, and you're left on your own to solve the riddle of the four books.
If you're not sure, or want someone to tell you, simply speak to Tar-Meena 4 times on 4 different days and she'll give you the clue. It's not that hard however, simply put the first letter of each paragraph next to one another and you get a special sentence:
Green emperor way where tower touches midday sun
Basically, this means go to the green emperor way right there in the city (it's the road around the palace), wait untill noon and then look at the surface of the only unnamed column in there. A map will light up and clicking on it will give you the location of your next quest; Lake Arrius Caverns.
No need to even report back to Jauffre, though you can if you so wish.
