Louis Letrush

Louis Letrush is an NPC located within the Bee and Barb Inn in Riften. When you first meet him at the Inn he gives the player the quest Promises to Keep, in which the Dovahkiin must steal Sibbi Black-Briar's horse, named Frost, and give it to him.

After the quest, depending on which paths were taken, Louis Letrush can be the trigger of some random encounters:

Even if he's not dead, this is the last time Louis Letrush can be found.
 * In case Maven Black-Briar was informed about Louis Letrush's plans, the encounter will show a hired Thug attacking Louis Letrush. This will also occur if Maven was not informed, the quest was carried to completion, and Louis was given the horse. If the Dovahkiin kills the Thug before he kills Louis, then Louis will attack. On the other hand, if the Dovahkiin kills Louis before the Thug gets to him, The Rift bounty will increase and the Thug will go away.
 * In case the Dovahkiin double-crosses Louis Letrush in order to keep Frost, a thug will come in the name of Louis to take revenge.

Quests


 * Promises to Keep

Bugs

 * If you talk to Louis, but do not accept the quest, but then talk to Sibbi Black-Briar about stealing Frost, Louis will vanish. You can still complete the quest, but you will not be able to talk to Louis until you deliver Frost to him.
 * After completion of the quest Promises to Keep, Louis Letrush can on occasion be found duplicated near the Whiterun Stables. Louis will duplicate up to a maximum of 4 times, one of which is stuck in the ground. Although permanent, this bug has no known, negative effects except for it being highly annoying at times.
 * Another duplicate can be found wandering near Knifepoint Mine. Oddly this duplicate cannot be killed, which if taken advatage of can be an infinite source of combat experience.
