Lambert spoke to Phillips. "I'm starving to death and I think Miss Crawford must be, too. Will you tell Felix to bring us some food, plenty of it?"
One of the sleuths went to the kitchen to give the order. Lambert turned to Morgan.
"How did you manage to bring us back?" he asked.
organ shrugged. "It was all guess work at the last. I at first could check the apparatus by your notes, and this took some time. You know you have written me in detail about what you were working on, so when I was summoned by Detective Phillips, who said you had mentioned my name to him as the only one who could help, I could make a good conjecture as to what had occurred. I heard the stories of all concerned, and realized that you must have dematerialized Miss Crawford by mistake, and then, unable to bring her back, had followed her yourself.
"I put on your insulation outfit, and went to work. I have not left here for a moment, but have snatched an hour or two of sleep from time to time. Detective Phillips has been very good and helpful.
"Finally, I had everything in shape, but I reversed the apparatus in vital spots, and tried each combination until suddenly, a few minutes ago, you were re-materialized. It was a desperate chance, but I was forced to take it in an endeavor to save you."
Lambert held out his hand to his friend. "I can never thank you enough," he said gratefully. "You saved us from a horrible fate. But you speak as though we had been gone a long while. Was it many hours?"
"Hours?" repeated Morgan, his lips parting under his black beard. "Man, it was eight days! You have been gone since a week ago last night!"
