"Oh, I'm all right now," Walter said, "with the exception of a certain shakiness and a splitting headache. It must have been a pretty severe dose that our interesting friend gave me last night. But I don't think there is any occasion to worry about me."

"Then we will have some breakfast, and get up to London at once," Venables said, in his quick, decisive fashion. "We can leave Lord Ravenspur and Miss Rayne here till we come back. I don't think that Lord Ravenspur has anything to fear from his enemy now."

Breakfast was despatched without delay, and immediately Venables and Walter left for London. The house was now quiet and still, for as yet practically nothing was known as to the cause of Silva's action, and public curiosity still slept.

It was some time after luncheon before Vera had a chance of speaking to the nurse, with an inquiry as to how the patient was getting on. The nurse smiled in reply.

"He is slightly better," she explained; "in fact, he is as well as he is likely to be. He has been conscious for the last half hour. He seems to want something, only I can't understand what it is. We may be able to find out when the doctor comes."

A RAY OF LIGHT.

It was no difficult matter to find Mrs. Delahay, who, when the late startling developments were laid before her, made no demur in giving her sister's address. Maria Delahay was looking just as pale and haggard as usual. It seemed impossible to rouse her from the state of apathy into which she had fallen. When the two friends were standing on the steps of the hotel they ran against Inspector Dallas.

"Any fresh news?" Walter asked.

"Well, no," Dallas admitted. "I am simply waiting on events at present. If you could only get Mrs. Delahay to be more candid with me it might save her a deal of unpleasantness in the long run."
