“Lenora’s gone up to the Professor’s again this afternoon. She is going to try and get hold of Craig and lock him in the garage. If she succeeds, she will send a message by wireless at three o’clock. It is half-past two now.”

“Well?” Quest exclaimed. “Well?”

“You can work this guard, if you want to,” Laura went on. “I have seen you tackle much worse cases. He seems dead easy. Then let me in the cell, take my clothes and leave me here. You did it before when you were trying to hunt down those men in Chicago, and not a soul recognised you.”

Quest followed the scheme in his mind quickly.

“It is all right,” he decided, “but I am not at all sure that they can really hold me on the evidence they have got. If they can’t, I shall be doing myself more harm than good this way.”

“It’s no use unless you can get hold of Craig quickly,” Laura said. “He is getting the scares, as it is.”

“I’ll do it,” Quest decided. “Call the guard, Laura.”

She obeyed. The man came good-naturedly towards them.

“Well, young people, not quarrelling, I hope?” he remarked.

Quest looked at him steadfastly through the bars.
