Unfortunately, while Mareth was able to relax long enough to recover her spells, her chance to rest would be cut short by a few quiet sounds from outside.  It was clear that at least two people were walking around outside her house, trying to be quiet, though thankfully not quiet enough.  Both of the people she could hear were on the same side of the house as the door to the alchemy shop, one of them likely right by the door, the other about twenty feet away, closer to the corner of the building.
