"We have two of your friends in limbo," returned Harry. "You will find it no holiday affair to keep a house for the purpose of murder and robbery. Never mind, you need say nothing, for it will not better matters in the least. Come;" and Harry Bernard led the old woman from the cellar.

A patrol wagon bore the prisoners to the lock-up, and Bernard had Dyke Darrel taken to a private hospital, where he could have the best of care. It was some days, however, before the badly battered detective came to his senses sufficiently to converse on the subject of the racket in the building on Clark street.

"My soul! Harry, has nothing been discovered of poor Nell?—was she killed?" questioned the wounded man in a voice wrung with anguish.

"I don't think Nell was mortally hurt," returned Bernard in a reassuring tone, although he hardly felt hopeful himself. "If she was, why should the villains have taken her away, or the villain rather, since, from your account, I judge that but one of them escaped, and he the man with the red hair."

"Yes, he seemed the chief scoundrel among them. I heard him called Professor Ruggles."

"He is about as much a professor as I am," answered Bernard.

"HE is the man we want for that midnight crime on the express train. I have evidence enough now, Dyke, to prove that this man is the guilty principal, and I also believe that one of his accomplices is now in prison."

"Indeed!"

And then the detective groaned in anguish of spirit and of body. It was hard to lay here, helpless as a child, while the fate of Nell was uncertain, and there was so much need for a keen detective to be afloat. Harry realized how his friend suffered, and soothed him as best he could. "Leave no stone unturned to find her, Harry," urged the detective. "If you do find and save her, great shall be your reward. If she is dead, then I will see about avenging the deed."

"And in that you will not be alone," assured Harry Bernard, a moist light glittering in his eye. Even Dyke Darrel did not suspect how deeply his young friend was interested in the fate of Nell.
