John closely examined this advertisement, and the other two, which were similar.

"Do you think she is in debt, sir?"

"Beecher Monmouth's a rich man," answered Dacent Smith, "with big interest in the timber business. However, one never knows what an extravagant woman may succeed in spending. I think it may be worth your while, Treves, to follow up the trail of this advertisement. I want you to apply yourself assiduously to the cultivation of this lady for the present. And keep well in mind the fact that, though her letters show nothing, she is yet conveying news regularly to the enemy."

CHAPTER XXI

Two evenings later Mrs. Beecher Monmouth's Spanish maid came to the door of her mistress's boudoir, knocked, and entered quietly.

"Doctor Voules is here, madam."

"I told you, Cecily, I was not at home!" said Mrs. Beecher Monmouth. "I don't want to see Doctor Voules—I don't want to see anybody!"

"But, madam," protested the maid, "it would be impossible to refuse to see Doctor Voules!"

Something took place between mistress and maid—an exchange of glances—which seemed somewhat to alter Mrs. Beecher Monmouth's mood of irritation.

"Very well, Cecily, let him come up." And when Cecily had departed to summon Doctor Voules, Mrs. Beecher Monmouth went to her low Turkish table, lit a buff-coloured cigarette, and stood with her back to the hearth, smoking somewhat more rapidly than usual. A knock came at the door, and Doctor Voules entered. He strolled into the apartment with his shoulders well back, his heavy chin thrust forward, the smile that sat so ill upon his harsh face was well in evidence.
