“We will go together to the spot to-morrow, Miss Sandys,” he said. “People think I’m telling a fairy story about the girl. But I assure you I’m not. I held her in my arms and stroked her hair from her face. I remember every incident of that tragic discovery.”

“Very well,” said the girl. “I’ll be here at ten o’clock, and we will go together. Now remain quiet and rest,” she urged with an air of solicitude. “Don’t worry about anything—about anything whatever,” she added with emphasis. “We shall clear up this mystery and bring your enemies to book without a doubt.”

And with that Roddy Homfray had to be satisfied, for a few moments later she buttoned up her warm fur coat and left, while old Mrs Bentley went upstairs and prepared his bed.

His friend Denton called again after he had retired, and found him much better.

“You’re pulling round all right, Roddy,” he laughed. “You’ll be your old self again in a day or two. But what really happened to you seems a complete enigma. You evidently fell into very bad hands for they gave you a number of injections—as your arm shows. But what they administered I can’t make out. They evidently gave you something which acted on your brain and muddled it, while at the same time you were capable of physical action, walking, and perhaps talking quite rationally.”

Then Roddy told his chum the doctor of the weird but misty recollections which from time to time arose within him of having been compelled to act as the handsome woman had directed. Exactly what he did he could not recall—except that he felt certain that while beneath the woman’s influence he had committed some great and terrible crime.

“Bah! my dear Roddy?” laughed Denton as he sat beside the other’s bed. “Your nerves are all wrong and awry. After those mysterious doses you’ve had no wonder you’re upset, and your imagination has grown so vivid.”

“I tell you it isn’t imagination!” cried Roddy in quick protest. “I know that the whole thing sounds utterly improbable, but—well, perhaps to-morrow—perhaps to-morrow I can give you some proof.”

“Of what!”

“Of the identity of the girl I found dying in Welling Wood.”
