Frank looked puzzled.
"But how did it come there?" he asked. "Why should it be left there?"
"I have known children to throw off coats or jackets on a hot day," smiled Ned. "I imagine that princes are not different from other children."
Ned went on with his examination of the pictures. At last he came to one which was badly torn, almost half of it being missing.
"There," he said. "This is a picture taken right there at Chimney rock. Do you see the face above it?"
The face referred to was not that of either of the two men Jimmie had been captured by, or of Bradley, who sat scowling just beyond reach of their voices.
"That is the man we want," Ned said, with a sigh. "If we had the other part of the picture we should see the boy looking over the rock, close at the man's side."
"Very close!" Frank observed. "They seem to have hold of hands.
Doesn't that look like a closed hand down lower?"
"That is just what it is!"
Ned laid the picture aside and Frank brought out those which had been made from the films taken from the baby camera. There were half a dozen of them and all were remarkably good.
