Stealing Frost ' s Lineage Papers . When arriving to the Black - Briar Lodge , there will be two to three mercenary guards outside in front of the lodge ; an archer and a swordsman . One option is to approach from the front and fight them as to enter through the front , or , sneak around and open the basement door on the west side of the house . If a third mercenary does not join the fight outside from the basement , there may be two in the basement area . Alternately , the building can be approached from the rear . The Lodge is set back against a hill that runs along the west side of the building and out toward the road to the south . The sneak skill can also be put to good use here , as there is a small path on the east side of the hill mentioned above . Behind the Lodge there is a wooden lookout tower and a single guard that walks between the two buildings . Kill the guard , take the key and enter from the back door ( north side - top building level ) . No matter what approach is taken , the objective is to steal Frosts ' identity papers , so the Black - Briar Lodge must be entered . The lodge is a three level building ; there are living quarters and rooms above , a dining area and rooms at mid - level and storage rooms and living quarters in the basement level . All outside guards appear to carry keys to unlock the doors of the Lodge . A single guard may be in the upper level and three to four guards in the mid / dining room level . In the upstairs bedroom , there is a Stone of Barenziah on a night - table . Once downstairs , there will be a barrel in the back with the papers in a strongbox . The papers may also be found on one of the tables . Stealing Frost . After Frost ' s identity papers have been retrieved , go outside to retrieve Frost ; he will be outside either in or behind the stables running around loose . Mount Frost and proceed to Letrush , who is close by . Returning to Louis Letrush . If Frost dies on the way to Louis Letrush , the quest fails . There are no scripted enemies on the way , but standard random encounters may still occur , in which case hostile enemies will target both Frost and the Dragonborn . If a random encounter which involves combat occurs nearby Louis , he will join in the combat , preventing the completion of the quest until he has left combat and the enemies have been defeated . If a random dragon encounter occurs , riding Frost at a very slow pace may avoid catching the dragon ' s attention . After getting to Louis Letrush , initiate a conversation with him which will give several dialogue options . There are several options to complete the job Letrush has given and to finish the deal . The first ( and easiest ) way is to simply accept the payment and give Frost to Letrush , completing the job Letrush has given and the quest itself . A second option is to persuade him to give the payment and also to keep the horse . There are two sub options , and may be based on whether or not the Dragonborn has already spoken with Maven . The first option is to threaten to report to Maven unless allowed to keep the horse , the second is to threaten to kill him to keep the horse . The first results in a response from him that " You play a dangerous game " and he leaves the Dragonborn the horse and walks away . If his life is threatened , he comments , leaves the horse and runs away . In both cases the Dragonborn has the horse and got the gold as well . Louis will however send a hired thug in retaliation . The thug will randomly show up at a later point saying that " this is for betraying Louis Letrush " before attacking . A third option to receive the reward is to demand the pay by intimidation in which the payment is received and the horse is given to Letrush which will result in a reward of leveled gold . A fourth option is to just kill him , then retrieve the horse and loot the gold off his body .
