Lady Jane did go out unresisting, hurriedly, and weeping bitterly.

Old Donica glanced almost guiltily over her shoulder; the nurse was hastening to the outer door. "Say nothing of us," she whispered, and shut the study door.

"Come, Miss Jennie, darling; do as I tell you. They must not know."

They crossed the floor; at her touch the false door with its front of fraudulent books opened. They were now in a dark passage, lighted only by the reflection admitted through two or three narrow lights near the ceiling, concealed effectually on the outside.

The reader will understand that I am here describing the architectural arrangements, which I myself have seen and examined. At the farther end of this room, which is about twenty-three feet long, is a niche, in which stands a sort of cupboard. This swings upon hinges, secretly contrived, and you enter another chamber of about the same length. This room is almost as ill-lighted as the first, and was then stored with dusty old furniture, piled along both sides, the lumber of fifty years ago. From the side of this room a door opens upon the gallery, which door has been locked for half a century, and I believe could hardly be opened from without.

At the other end of this dismal room is a recess, in one side of which is fixed an open press, with shelves in it; and this unsuspected press revolves on hinges also, shutting with a concealed bolt, and is, in fact, a door admitting to the green chamber.

It is about five years since I explored, under the guidance of the architect employed to remove this part of the building, this mysterious suite of rooms; and knowing, as I fancied, thoroughly the geography of the house, I found myself with a shock of incredulity thus suddenly in the green chamber, which I fancied still far distant. Looking to my diary, in which I that day entered the figures copied from the ground plan of the house, I find a little column which explains how the distance from front to rear, amounting to one hundred and seventy-three feet, is disposed of.

Measuring from the western front of the house, with which the front of the Window dressing-room stands upon a level, that of the green chamber receding about twelve feet:—

I never spoke to anyone who had made the same exploration who was not as much surprised as I at the unexpected solution of a problem which seemed to have proposed bringing the front and rear of this ancient house, by a "devilish cantrip slight," a hundred feet at least nearer to one another than stone mason and foot-rule had ordained.
