CHAPTER II.

NICK IS BOLDLY CHALLENGED.

Nick knew the old Plummer mansion well. There is not a house to match it in this country.

A hundred years and more ago it must have been the scene of strange adventures. It was built, certainly, by one who did not expect a peaceful and quiet life within it.

The thick stone walls, which look so unnecessarily massive, are really double. There are secret passages and movable panels and trap-doors enough in that house to hide a man, if a regiment of soldiers was after him.

Evidently such a place offered every chance to shrewd criminals who might have a motive for playing upon the superstitious beliefs of the present proprietor.

Anybody who couldn't get up a respectable ghost in the old Plummer house must be a very poor fakir.

The mere fact that all the doors and windows of a room were closed did not prevent any person from going in or out at will, if he knew the secrets of the house.
