arry and Tina—anything but ghosts, very much alive and very much perturbed—were standing back of that tree. They saw the British officers reading the scrap of paper. They could hear only the words, "Mary," and "from Mistress Atwood."
"A message!" Larry whispered. "She and George must have found a chance to write it, and dropped it here while the Robot murdered Major Atwood!"
Larry and Tina vehemently wanted to read the note. Tina whispered:
"If we show ourselves, they will be frightened and run. It is nearly always so where Harl and I have become visible in earlier Times."
"Yes. I'll try it."
Larry stepped from the tree, and shouted, "Drop that paper!"
And a moment later, with Mary's torn little note scribbled on a scrap of paper thrust in his pocket, Larry ran with Tina from the Atwood garden. Unseen they scurried back through the field. Under a distant tree they stopped and read the note.
"2930!" Larry exclaimed. "The Robot is taking them back to your world, Tina!"
"Then we will go there. Let us get back to Harl, now."
But when they reached the place where they had left the cage, it was not there! The corner of the field behind the clump of shadowing trees was empty.
