"Do you mean that she is in danger?" Venables asked.

"I think you can see that for yourself, sir," Dallas replied. "Naturally, I am hesitating as long as possible----"

"Then hesitate a little longer," Walter said. "Quite by accident Lord Ravenspur has stumbled upon a clue which I think will astonish you when you come to know his story. We are going off now to a place called Cannon Green. We shall probably be back by the last train tonight, and I want you to meet us at Waterloo Station. I think you will be well rewarded for your trouble."

Dallas promised, and, like the wise man he was, asked no questions. The two companions proceeded in a cab to Isleworth Road, where they asked to see the mistress of the house. The maid who answered the door was somewhat reticent, but she admitted that her mistress was at home, whereupon Walter and his companion entered without further ceremony. Perhaps their manner impressed the maid, for she came back a moment later saying that her mistress would see the visitors. The Countess entered the drawing-room and glanced with cold displeasure at the intruders.

"What can you possibly want with me?" she demanded.

"Perhaps I had better explain," Walter began. "My name is Lance, and I am a nephew of Lord Ravenspur. Lord Ravenspur has a ward who is called Miss Vera Rayne. In other words, I understand that Miss Rayne is really your daughter."

The Countess's cold face flushed slightly.

"I am not prepared to contradict you," she said.

"My dear madam," Walter said, "this is no time for diplomacy. Rightly or wrongly, my uncle came to Italy eighteen years ago and kidnapped your daughter. You see, I am quite candid, and I hope you will be good enough to be as candid in your replies. My uncle will himself explain why he took this bold step, but I understand that your late husband did not consider you a desirable parent for a child, and he made my uncle promise to remove the child from your influence. Into the morality of that question I am not disposed to go. For nearly eighteen years nothing happened, and my uncle began to regard Vera quite as his own child. Then the truth came out, and some emissary of yours came to England, prepared to go to any length to regain possession of your daughter. I need not say I am alluding to the man called Silva, also known to many people as Valdo, the flying man. This servant of yours made no fewer than three attacks on my uncle's life, none of which, fortunately, was successful. And then, I understand, you came on the scene. I believe you were instrumental in luring your daughter from Lady Kingmar's the night before last, and getting her imprisoned at a place called Cannon Green. One moment, please. I would not deny it, if I were you----"

"I am not going to deny it," the Countess said in a hard, dry voice. "There is no occasion to."
