Tip, listening, put in a suggestion.

“Let one o’ them that’s been fetchin’ kangaroos and apes take it. Then radio who’s in the possessive case. Let them get the Voice of Doom after them.”

“Tip and I could take it in an airplane,” Roger hinted eagerly.

“There is only one logical course open,” Grover gave final decision, “hold everything static. Make no move. Safeguard Doctor Ryder, with the same type of protection we have given the safe, in a modified form. Then, when the promised Doom arrives, its emissaries can be informed that if they furnish proper credentials they may have their Eye of Om.”

Tip looked as disappointed as did Roger.

No Tibet? No adventure? No thrills?

“I suppose,” Doctor Ryder shrugged, “it is the sure way, though not too safe for me, no matter what devices you arrange. If you knew the hidden forces of Nature that those Lamas can call into play, modern scientific protection would be as useful as a child’s toys to combat unseen dangers that strike through the air.”
