The children walked down the room admiring the delicate iron work of the locks, for which Aline had a great fancy and she had paused at one, which was her particular favourite, and was fingering every part of it affectionately, when she noticed that a small sculptured figure was loose and could be made to slide upwards. This excited her curiosity and she pushed it to and fro to see if it was for any special purpose, till suddenly she discovered that, when the figure was pushed as high as it would go, the whole lock could be pulled forward like a little door on a hinge, revealing a small cavity behind. Both children started and peered eagerly into the space disclosed, where they found a very thin little leather book which was dropping to pieces with old age. They took it out and examined it and found that the cover had separated so as to lay open what had been a secret pocket in the cover, which contained a piece of stout parchment the same size as the pages of the book. The book was written in black letter and was in Latin. “Now you see the use of knowing Latin,” said Aline triumphantly, with a twinkle in her dark blue eyes. “That depends whether it is interesting,” Audry replied. “It seems to be an account of the building of Holwick Hall; but what is the use of this curious piece of parchment with all these holes cut in it?” “Perhaps you can find out if you read the book,” suggested Audry. “It certainly must be of some importance or they would not have taken all that trouble to hide the book and also the parchment in the book. Let us sit down and see what you can make of it.” So they sat down and Aline was soon deeply interested in the account of the building, how the great dining hall was erected first, then the buttery, pantry and kitchen and afterwards the beautiful solar. Audry found her interest flag; although, when it came to the building of her room and the cost of the different items, she brightened up. “Still,” she said, “I do not see why all this should be kept so secret; any one might know all that we have read.” There was one thing that seemed to promise interest, but apparently it led to nothing. At the beginning of the book was a dedication which could be translated thus: “To my heirs trusting that this may serve them as it has served me.” But in what way it was to serve them did not appear, and the evening was closing in and it was getting dark, but the children were as far as ever from discovering the meaning of the phrase or of the parchment with the holes. “Let us take it to our room,” Aline said at last; “it is not chained like the others. We can hide it in the armoire and read with the little lamp when the others have gone to sleep and no one is likely to come in.” So they put the piece of parchment to mark the place, ran to their room and hid the book and went to join the rest of the family.
