Naah. They've entered the mansion, bats flew out as they opened the door, once the bats were gone they walked inside, it was really dark, and now the curtains have been pulled off to reveal an incredibly dusty corridor. Oh and all doors in the specific corridor are locked at the moment. (Short summary is short.)
And yes, it is weird that a corridor starts just as they walk into the building instead of them coming into a hall or some other big room. But that will be explained eventually x3
