But it was unlikely that sister would have keys. He looked thoughtfully at the table. Something of a connoisseur, he judged it as belonging to the adolescence of the last century.

A desk more than a hundred years old! A mysterious, sinister woman searching in it! “A hundred to one on. Secret Drawer!” thought Anthony, and probed among the pigeon-holes. He met with no success, and felt cheated. His theory of the essential reality of story-books had played him false, it seemed.

Loath to let it go, he tried again; this time pulling out from their sheaths the six small, shallow drawers which balanced the pigeon-holes on the other side of the alcove containing the ink-well. The top drawer, he noticed with joy, was shorter by over an inch than its five companions. He felt in its recess with long, sensitive fingers. He felt a thin rim of wood. He pressed, and nothing happened. He pulled, and it came easily away. The Great Story-book Theory was vindicated.

He peered into the unveiled hollow. It was filled with papers, from their looks recently tossed and crumpled.

“Naughty, naughty Laura!” said Anthony happily, and pulled them out.

There were letters, a small leather-covered memorandum-book, a larger note-book and a bunch of newspaper-cuttings.

He pulled a chair up to the table and began to read. When he had finished, he replaced the two little books and the letters. They were, he judged, unimportant. The newspaper-cuttings he retained, slipping them into his wallet. The illegality of the proceeding did not apparently distress him.

He replaced the little drawers, careful to leave things as he had found them. On his way to the door, he paused to examine the little polished rosewood table which stood beside the grandfather clock and was the fellow of that which supported the two tall vases he had spoken of to Boyd. A blemish upon its glossy surface had caught his eye.

On close inspection he found a faint scar some twelve inches long and two wide. This scar was compounded of a series of tiny dents occurring at frequent and regular intervals along its length and breadth.

Anthony became displeased with himself. He ought to have noticed this on his first visit to the room. Not that it seemed important—the wood-rasp had obviously been laid there, probably by the murderer, possibly by some one else—but, he ought, he considered, to have noticed it.
