"Expected her!" cried Diana, thunderstruck. "Impossible!"

"I don't know so much about that," replied Lucian drily, "although I admit that on the face of it my assertion appears improbable. But when I met your father the second time, he was so anxious to prove, by letting me examine the house, that no one had entered it during his absence, that I am certain he was well aware the shadows I saw were those of people he knew were in the room. Now, if the woman was Mrs. Vrain, she must have been in the habit of visiting your father by the back way."

"And Ferruci also?"

"I am not sure if the male shadow was Ferruci, no more than I am certain the other was Mrs. Vrain."

"But the veil?"

Lucian shrugged his shoulders in despair. "That seems to prove it was she," he said dubiously, "but I can't explain your father's conduct in receiving her in so secretive a way. The whole thing is beyond me."

"Well, what is to be done?" said Diana, after a pause, during which they looked blankly at one another.

"I must think. My head is too confused just now with this conflicting evidence to plan any line of action. As a relief, let us examine your friend and hear what she has to say."

Diana assented, and touched the bell. Shortly, Miss Tyler appeared, ushered in by a nervous waiter, to whom it would seem she had addressed a sharp admonition on his want of deference. Immediately on entering she pounced down on Miss Vrain like a hawk on a dove, pecked her on both cheeks, addressed her as "my dearest Di," and finally permitted herself, with downcast eyes and a modest demeanour, to be introduced to Lucian.

It might be inferred from the foregoing description that Miss Tyler was a young and ardent damsel in her teens; whereas she was considerably nearer forty than thirty, and possessed an uncomely aspect unpleasing to male eyes. Her own were of a cold grey, her lips were thin, her waist pinched in, and—as the natural consequence of tight lacing—her nose was red. Her scanty hair was drawn off her high forehead very tightly, and screwed into a cast-iron knob at the nape of her long neck; and she smiled occasionally in an acid manner, with many teeth. She wore a plainly-made green dress, with a toby frill; and a large silver cross dangled on her flat bosom. Altogether, she was about as venomous a specimen of an unappropriated blessing as can well be imagined.
