This is a mod I made for myself and decided to share.  I really love Elianora's Marlborough Mansion.  I wanted a little company in that sweet little place.  So, I made a vendor to keep the Sole Survivor from getting lonely.

Babette is a voiced vendor.  She uses a slightly modified version of Trashcan Carla's merchant inventory.  The Marlborough House is an unmarked location just a few hundred feet west of HalluciGen, Inc.

Only the base Fallout 4 is required.  This shouldn't conflict with anything.  If you use a mod, like Elianora's Marlborough Mansion, that modifies that location.  Put this mod above that mod in the load order.

Thanks go out to Elianora for the mansion and to Bethesda for the game!
