I felt the sudden impingement of Hezekiah's slipper upon my own conscience, if I may so state the matter. Hezekiah, playing ghost, had confessed to me that she had visited Cecilia's room. Hezekiah, amusing herself with the library chimney and frightening the servants by stealing into the forbidden house through the coal-hole, was a culprit to be scolded and forgiven; but what of Hezekiah mischievously filching an article of real value to her sister! I did not like this turn of affairs. I must get back to the roof, find Hezekiah, and compel her to return the silver book. Only by tactfully managing this could I serve well all the members of the house of Hollister. But first I must leave Cecilia with a tranquil mind.

"I thank you for confiding this matter to me, Miss Hollister. Please do not attach suspicion to any one until I have seen you again."

"But if you should be unable to restore"—

"I assure you that the book is not lost. It has been mislaid, that's all. I shall return it to you at breakfast. I give you my word."

"Do you really mean it?" she faltered. "Please keep this from Aunt Octavia! I can't tell you how important it is that she be kept in ignorance of my loss. The consequences, if she knew, might be very distressing."

I could not for the life of me see what great importance could attach to those few leaves of paper in their silver case, but if Miss Octavia and Hezekiah were interested in it as well as Cecilia, it must have a significance wholly unrelated to its intrinsic value. It is the way of professional detectives to suggest impossible theories merely to conceal their own plans and intentions, and as I had reached a point where my tongue was astonishingly glib in subterfuge and evasion, I suggested that it might perhaps have been one of the new servants, or indeed the Swedish maid.

"We will look into the matter, Miss Hollister. At breakfast I shall have something to report. Meanwhile silence is the word!"

Miss Octavia was carrying the invincible John Stewart Dick away to the billiard-room. He glared at me murderously as he trailed glumly after the lady of the manor. The others were crowding about Cecilia again, and I yielded to them willingly. As I sauntered toward the door Ormsby detained me a moment. His manner was arrogant and he hissed rather than spoke.

"I'm directed to command your presence at the Prescott Arms to-morrow at twelve o'clock. The business is important."

"I regret, my dear brother, that I shall be unable to sit with you at that hour in committee of the whole, and for two reasons. The first is that I am paired with Lord Arrowood. You refused to take him into your base compact, and allowed him to be thrown out of the inn for not paying his bill. The act was deficient in generosity and gallantry."
