“She’s not coming back at all,” answered the old woman, “she told me to tell you she could not stop, sir. And she wouldn’t let me disturb you, neither, sir.”

“But did she leave no note or anything for me?” asked Desmond.

“No, sir,” answered old Martha as she folded up the cloth.

Gone! Desmond stared gloomily out at the sopping garden with an uneasy feeling that he had failed in his duty.

CHAPTER XIII.
WHAT SHAKESPEARE’S COMEDIES REVEALED

In a very depressed frame of mind, Desmond turned into the library. As he crossed the hall, he noticed how cheerless the house was. Again there came to him that odor of mustiness—of all smells the most eerie and drear—which he had noticed on his arrival. Somehow, as long as Nur-el-Din had been there, he had not remarked the appalling loneliness of the place.

A big log fire was blazing cheerfully in the grate, throwing out a bright glow into the room which, despite the early hour, was already wreathed in shadows. Wearily Desmond pulled a big armchair up to the blaze and sat down. He told himself that he must devote every minute of his spare time to going over in his mind the particulars he had memorized of Mr. Bellward’s habits and acquaintanceships. He took the list of Bellward’s friends from his pocket-book.

But this afternoon he found it difficult to concentrate his attention. His gaze kept wandering back to the fire, in whose glowing depths he fancied he could see a perfect oval face with pleading eyes and dazzling teeth looking appealingly at him.

Nur-el-Din! What an entrancing creature she was! What passion lurked in those black eyes of hers, in her moods, swiftly changing from gusts of fierce imperiousness to gentle airs of feminine charm! What a frail little thing she was to have fought her way alone up the ladder from the lowest rung to the very top! She must have character and grit, Desmond decided, for he was a young man who adored efficiency: to him efficiency spelled success.

But a spy needs grit, he reflected, and Nur-el-Din had many qualities which would enable her to win the confidence of men. Hadn’t she half-captivated him, the would-be spy-catcher, already?
