SpeechSkill BookThe Buying Game - Go up the first ramp from the entrance, follow it until reaching the stairs, turn left at the stairs, follow that shelf around and the book is on top of one of the three crates.

East Empire Trading Map - In the dockmaster's office behind the ship, at the top of a dirt ramp. Note that there are also multiple pieces of jewelry as well as gold here.
There is a chest with a leveled amount of gold outside of the warehouse, underwater. To get to it, walk off the boardwalk at the stairs closest to the warehouse and look north.
After the completion of Scoundrel's Folly, the East Empire Wardens who patrol the warehouse will be replaced by the average Solitude guards.
Unlike the East Empire Wardens who attack on sight, the Solitude guards allow for a ten-second trespass warning before attacking or arresting.
The name "East Empire Company" is likely a reference to the "East India Company," a 17th-19th Century English trading company.
The interior portion of the East Empire Company Warehouse is considered outdoors, therefore it is possible for a dragon to spawn inside. However, it will clip through the walls.
Teldryn Sero tends to call the company "Heartless Bastards."
It is possible that East Empire Warden might send hired thugs if Dragonborn steals anything from the warehouse.
It is not necessary for the player to have joined the Thieves Guild and started the quest "Scoundrel's Folly" to gain entrance to the warehouse; one needs to simply pick the lock on the door. However, both the outside and interior is guarded by Solitude guards, as well as some dockworkers on the boats. Being caught trespassing will yield a 5 bounty, whilst killing any of the inhabitants within gives the usual 1000 bounty for each kill. Having a follower along, such as Cicero or a Housecarl, will allow them to fight the guards and dockworkers while the player can remain undetected to avoid high bounties. The player must have a high Sneak skill to avoid detection, however.
